Inverse Trig Functions Calculator
Top
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).

  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.



    Answer  :  

    $\therefore$ 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



    Answer  :  

    The value of tan-10.5 = 30o = 0.523 radians.
