Inverse trigonometric functions are the inverse values of trigonometric functions given as sin-1, cos-1, tan-1, sec-1, cosec-1 and cot-1 (inverse of the trigonometric function).
Inverse trig Functions Calculator calculates the inverse trigonometric function of the value entered in the given space in degrees and also converts it in to radians.The range of the value should lie between (-1,+1).

## Steps for Inverse Trig Functions Calculator

Step 1 :

Read the problem and observe which trignomectric function is to be found. Take that value as $\theta$.

Step 2 :

Observing the log table get the value of given function in degrees and also convert it into radians.

## Problems on Inverse Trig Functions Calculator

1. ### Find the value ofInverse sine and cosine function of 1.

Step 1 :

Given: To find the value of trigonometric function sin-1 1 and cos-1 1.

Take $\theta$ = sin-11

=> sin $\theta$ = 1

also take $\theta$ = cos-11

=> cos $\theta$ = 1.

Step 2 :

Referring to log table we get

sin 90o = 1 => $\theta$ = 90= 1.5707 radians

cos 0o = 1 => $\theta$ = 0o= 0 radians.

$\therefore$ sin-11 = 90o = 1.5707 radians

and cos-11 = 00 = 0 radians.

2. ### Find the value of the given inverse function: tan-10.5.

Step 1 :

Given: To find the value of the given function tan-10.5

Take $\theta$ = tan-10.5

=> tan $\theta$ = 0.5.

Step 2 :

Referring to log table we get

tan 30o = 0.5 => $\theta$ = 30= 0.523 radians
