Why sine cannot measure angle larger than 45?
It can. The sine function is defined for all numbers--negative, 0, and positive. The function is periodic and repeats every 360 degrees.
Sine of an angle cannot be 2, as you must be knowing, sin90=1, u may conclude that sin180=2. but 180 degree cannot be an angle of a triangle,
-1 < sine(theta) < 1 so sine(theta) cannot be 3125
tangent will always be larger because its denominator is smaller than sine's.
to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle… Read More
The formula is a/sinA=b/sinB=c/sinC. The idea behind the equation is that the larger an angle is the larger the side across from it will be and the smaller the angle the smaller the side across from it will be.
No. The sine of an angle is not directly proportional to the angle. It is a function of the angle, but it is periodic, repeating every 360 degrees of the angle.
the sine of a 30 degree angle is 0.5
the sine of an angle can't be greater than 1.0
50° angle measure 50° m?= 50° replace the question mark with the line's name, or what the line is called.
There is not a "correct" trigonometric ratio. The one based on right angled triangles are limited to right angled triangles and so cannot be used for angles greater than pi radians (180 degrees). This is despite the fact that the sine ratio is defined for any angle, including reflex angles or angles of negative measure. To find the sine of an angle of measure q, draw a line that makes that angle with the positive… Read More
Sine of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
The sine theta of an angle (in a right triangle) is the side opposite of the angle divided by the hypotenuse.
An angle can have a sine ratio, not a triangle.
Sine = opposite / hypotenuse
If you mean the sine function, it is dependent on an angle. For example, the sine of an angle of zero degrees is zero; the sine of an angle of 90 degrees is one; for an angle of 180 degrees, the sine is again 0; if you make a graph, you get a curve that looks like a wave. In general, the values the sine function can take are between 1 and -1, inclusive.
Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.
The angles of light are the result of the law of sines: sine( incidence angle)/speed of incidence = sine(refraction angle)/ speed of refraction
To find which angle has a sine of 0.13, you calculate arcsin or sin^-1(0.13) =7.47 degrees 7.47 degrees has a sine of 0.13. There is also another angle , below 360 , has a sine of 0.13. Subtract 7.47 from 180. 180-7.47 = 172.53 degrees also has a sine of 0.13.
The sine of 22.5 degrees is 0.383
No. As the angle increases from zero to 90 degrees, its sine increases from zero to '1'.
We'll answer your question as asked. What was asked was, "What is the sine of the angle (the angle theta) if the angle measures 0.4384?" That's the way the question reads. That's a pretty small angle. Less than one degree. That angle has about 0.00765 as the sine. Perhaps the question was "What is the angle of theta if its sine is 0.4384?" In the event that this was really your question, if sine theta… Read More
The absolute value of the sine function cannot exceed 1 and so sin(a) = 312 is not possible.
Sine of the angle to its cosine.
Sine and the cosine of the angle.
The relation between the angle of refraction and refactive index is: Sine i/Sine r=Refractive index where,i=angle of icidence r=angle of reflection
A is an angle whose sin is 37 and whose secant is negative Its vertex is the origin and one side is the positive x axis. What quadrant does the terminal side of the angle reach?
There is no such angle, since the sine of an angle cannot be greater than 1.
In a right triangle, the sine of an (non right angle) angle would the ratio of the opposite side (opposite to the angle selected) and the hypotenuse
The answer depends on what information you have, If you know only the lengths of the sides, you use the cosine rule to find the measure of one angle and then the sine rule to find the other angles.
The sine of an angle in a right triangle is opposite/hypotenuse, where opposite is the only side that is not adjacent to the angle you want to find the sine of, and the hypotenuse is the side opposite the right angle in the triangle. Just find opposite/hypotenuse.
It is: sine = opposite/hypotenuse
No angle has a sine function greater than 1.
type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine
No. The sine of an acute angle is less than 1. An acute angle is less than 90 degrees. The sine of 0 degrees is 0, and the sine of 90 degrees is +1. So the sines of the angles between 0 degrees and 90 degrees are less than 1.
sine bar is used to measure the angles of given work pieces
The longest side of the right angles triangle is called the hypotenuse. Divide the length of the side opposite the chosen angle by the length of the hypotenuse. This is the Sine of the angle.
A ski slope is 250 yards long with a vertical drop of 100 yardsfind the angle of depression of the slope?
The angle of depression is equal to the angle of elevation, so use the sine ratio to find the angle. sine = opposite (the vertical drop) divided by the hypotenuse (the ski slope) sine = 100/250 = 2/5 or 0.4 sine-1(0.4) = 23.57817848 degrees which is about 24 degrees
Sine = Opposite divided by Hypotenuse Opposite is the side of the triangle opposite the angle (in this case the 90o angle). Hypotenuse is the side opposite the right angle in a right angle triangle. Therefore, Sine 90 = 1 because the opposite side and the hypotenuse are the same side, they are both opposite the right angle.
at a 45 degree angle, or pi/4
In a right angle triangle divide the opposite by the hypotenuse to find the sine ratio.
Sine ratio = opposite/hypotenuse
sine(15 degrees) = 0.25882 (rounded)
Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index
The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.
First of all, a sine is the trigonometric function that is equal to the ratio of the opposite a given angle to the hypotenuse. The teacher told us to use the word sine in a sentence. He told us what a sine is and how you use it. A sine is the trigonometric function that is equal to the ratio of the opposite a given angle to the hypotenuse.
The sine is almost equal to the angle, in case the angle is expressed in radians. Please make a picture of a circle, put a point on the circle at a small angle (say, 10 degrees or less), then draw the sine (a vertical line from the x-axis up to your point) for a small angle. You will see that the arc of the circle has almost the same length as the vertical line you… Read More
Cosecant is the reciprocal of sine. To find the cosecant of an angle using a calculator, find the sine of that angle (using the Sin button) and then divide 1 by the result.
It is simply the sine of the supplementary angle. If x is an angle measuring (90, 180) degrees, then sin(x) = sin(180 - x).
sin(30) = 1/2
the ratio of the incident angle to the sine of the rafracted angle is constant
