The inverse sine function sin-1 takes the ratio opposite hypotenuse and gives angle θ. And cosine and tangent follow a similar idea. Example (lengths are only to one decimal place): sin (35°) = Opposite / Hypotenuse. = 2.8/4.9.
Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, [4] and are used to obtain an angle from any of the angle's trigonometric ratios. Inverse trigonometric functions are widely used in engineering, navigation, physics, and geometry.

12 sie 2024 · The key to simplifying expressions involving inverse trigonometric functions is to remember that the inverse sine, cosine, or tangent of a number can be treated as an angle. It can often clarify the computations if we assign a name such as \(\theta\) or \(\phi\) to the inverse trigonometric value.
The inverse trigonometric functions (sin -1, cos -1, and tan -1) allow you to find the measure of an angle in a right triangle. All that you need to know are any two sides as well as how to use SOHCAHTOA.
Sine, cosine, and tangent are the most widely used trigonometric functions. Their reciprocals, though used, are less common in modern mathematics. Trigonometric functions are also called circular functions. 6 trig functions. The table below shows the six trigonometric function values for the specified angles in both degrees and radians.
