Any number can be a tan. So -sqrt(17), 19.56, 45678942 are all examples of tan.
Cosine can have any value in the range [-1, 1].
How to solve sin of cos inverse of x?
sin[cos-1(x)] is an expression; it is not an equation (nor inequality). An expression cannot be solved.
1 and the positive and negative square roots of 2
Where does the word lattimore come from?
The name originated in Wales during the mid 1200's and was mostly 'transported' over to Ireland during the 1600's. In 1842, The first Irishmen with the surname Lattimore moved over to England in the attempt for work during the Industrial Revolution. Ever since then, the surname Lattimore has been mostly common in England, Ireland and Wales.
Fertilizers provide plants with?
Fertilizers typically add nitrates, phosphates and sulfates as well as salts of magnesium, potassium and calcium. They may also contain micronutrients of other metals.
What is the arc function for trigonometric relationships?
The trigonometric function of an angle gives a certain value
The arc trigonometric function of value is simply the angle
For example, if sin (30 degrees) = 0.500
then arc sine ( 0.500) = 30 degrees
How can you illustrate the definition of a circle?
A circle is a shape with a circumference of 360 degrees.
What is the formula for cone volume?
1/3 pi times r2 times height
that's the closest I could get on this thing
Where are angles used in real life?
They are ued all over the place for Ex. TV, oven, shelves, pizza, windows, mirrors, shoeboxes, and amything else like that.
If the sun is hitting a pole at 30 degrees altitude and the pole is 3' tall how long is the shadow?
If the pole is on level ground then you have the outline of a right angled triangle with an opposite side of 3 feet and an adjacent angle of 30 degrees. To find the length of the adjacent side (which in effect is the shadow of the pole) use the tangent ratio: tangent = opposite/adjacent which can be rearranged to: adjacent = opposite/tangent adjacent = 3/tangent 30o = 5.196152423 feet Therefore the shadow cast by the pole is 5.2 feet corrected to one decimal place.
How do you use the discriminant to find the number and type of zeros of a function?
If the discriminant is positive, then the function has two real zeros. If it is zero, then the function has one real zero. If it is negative, then it has two complex conjugate zeros.
This assumes that we are talking about a standard second order polynomial equation, i.e. quadratic equation, in the form Ax2 + Bx + C = 0, and that the discriminant is B2 - 4AC, which is a part of the standard solution of these kind of equations.
How do you find direction of a vector?
Consider the space defined by orthogonal unit vectors iand j. Let ai + bj be a vector in that space. Its direction is arctan(b/a) provided a � 0. If a � 0, the direction is pi/2 radians (or in the jdirection).
Angles are measured from the positive direction of the iaxis in the anticlockwise direction.
