Trigonometric function and inverse trigonometric function

  1. Trigonometric function:sin,cos,tan,cot,sec,csc
    • sin(π/6) >>>0.5

  2. Inverse trigonometric function: sin-1(x), cos-1(x), tan-1(x), cot-1(x), sec-1(x), csc-1(x) ,asin,acos,atan,acot,asec,acsc
    • sin-1(0.5) >>>0.523598775598299

    • asin(0.5) >>>0.523598775598299
