How to do inverse trig functions on calculator??

Answer in brief ...​

Answer 1

$\huge\bf{Answer:-}$

To do inverse trig functions on a calculator, enter the value and press either the arcsin, arccos and arctan buttons OR sin^{-1}, cos^{-1}, tan^{-1}sin

−1 ,cos −1 ,tan −1 buttons. The functions arcsin(x), arccos(x) and arctan(x) are the inverse functions of the 3 main trigonometric functions sin(x), cos(x), and tan(x) formed by a reflection across the line y=x. This results in the (x,y) points of sin(x), cos(x) and tan(x) switching their order (y,x) in each inverse

Further Explanation

Sine

A function is a rule that assigns exactly one output to each input. In trigonometry there are three main functions sine, cosine, and tangent based on the ratios of sides corresponding to angles within a right triangle. The sine function written as sin(x) has the input of an angle written in degrees or radians and an output as a specific ratio for that angle within a right triangle. The ratio for sine is opposite / hypotenuse. When graphed these inputs form a wavy graph that begins at the origin.

Cosine

The cosine function written as cos(x) has the input of an angle written in degrees or radians and an output as a specific ratio for that angle within a right triangle. The ratio for cosine is adjacent / hypotenuse. When graphed these inputs form a wavy graph that begins at its y-intercept (0,1).

Tangent

The tangent function written as tan(x) has the input of an angle written in degrees or radians and an output as a specific ratio for that angle within a right triangle.
