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 inverse (negatives) of sine, cosine, and tangent are used to calculate the angle theta (or whatever you choose to name it). Initially it is taught that opposite over hypotenuse is equal to the sine of theta sin(theta) = opposite/hypotenuse So it can be said that theta = sin-1 (opp/hyp) This works the same way with cosine and tangent In short the inverse is simply what you use when you move the sin, cos, or tan to the other side of the equation generally to find the angle
A way to remember the definitions of the three most common trigonometry functions: sin, cos and tan. Used as a memory aid for the definitions of the three common trigonometry functions sine, cosine and tangent.
Sine is a law in math that helps you find the length or angles in a triangle.Sin Equals:1/YLaw of Sines:Sin A/a = SinB/b = SinC/cCosine, tangent, cotangent, secant and cosecant are also used to find sides and angles of a triangle.
When an object is in orbit of another, its direction can be determined by drawing a tangent along its orbit.
That is not correct: they are always LESS-THAN-OR-EQUAL to 1. They are also always greater-or-equal to minus 1.The fact that this is so follows directly from the definition. Two different definitions are commonly used:1) The sine is the y-coordinate of a unit circle (a circle of radius 1, with center at coordinates (0, 0)). The cosine is the x-coordinate of the same circle. The highest point on the circle has the y-coordinate 1 (at 90 degrees).2) In a right triangle, the sine is the side opposite to the angle considered, divided by the hypothenuse. The hypothenuse is of course longer than the other sides (except in the extreme case of 0 or 90 degree angles - this would not be properly called a triangle).
in trigonometry
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
The inverse (negatives) of sine, cosine, and tangent are used to calculate the angle theta (or whatever you choose to name it). Initially it is taught that opposite over hypotenuse is equal to the sine of theta sin(theta) = opposite/hypotenuse So it can be said that theta = sin-1 (opp/hyp) This works the same way with cosine and tangent In short the inverse is simply what you use when you move the sin, cos, or tan to the other side of the equation generally to find the angle
because sine & cosine functions are periodic.

# HE USED LETTERS FOR UNKNOWN QUANTITIES. # WORKED ON THE APPROXIMATION OF "PI" TO 4 DECIMAL PLACES AND DEFINED IT AS IRRATIONAL. # GAVE THE AREA OF TRIANGLE AND CIRCLE. # DEFINED SINE, COSINE, VERSINE AND INVERSE SINE.
usually its used to find a missing angle or length of a right triangle. Of course there is more to trigonometry. any way you can use sine, cosine, and tangent, to fine the missing angle or length
If you mean 'sohcahtoa' then it is a memory aid for working out the properties of right angle triangles as follows:- Sine = opposite/hypotenuse Cosine = adjacent/hypotenuse Tangent = opposite/adjacent
SoH: used for finding the sine of a triangle in trigonometry: Opposite/HypotenuseCaH: used for finding the cosine of a triangle in trigonometry: Adjacent/HypotenuseToA: used for finding the tangent of a triangle in trigonometry: Opposite/Adjacent
You usually need all three primary functions. The sine and cosine functions are used to resolve the vector along orthogonal axes, and the tangent function is used to find its direction.
