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
- alexLv 74 months ago
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
