Mathematical question? ?

Suppose the function that converts x degrees into f(x) radians is f(x)= pi x/180

1) convert 120pi degrees into equivalent radians and find its smallest positive coterminal angle2) find f^-1(x) and explain what it signifies

    y = f(x) = πx/180


    f(120) = π*120/180 = 2π/3


    to find f^-1(x)


    x = πy/180 ---> y=(180/π)x ,  converts x radian to  degrees
