inverse of f(x)=arccos(x/2)

Solution

inverse

f (x) = arccos (\frac{x}{2})

Solution

2 cos (x)

Solution steps

arccos (a) = b \Rightarrow a = cos (b)

\frac{x}{2} = cos (y)

Solve for

x, \frac{x}{2} = cos (y)

2 cos (y)

Substitute

y = x

2 cos (x)

Popular Examples

extreme f(x)=2x^2-6 extreme points

f (x) = 2 x^{2} - 6

perpendicular y= 1/2 x-1 perpendicular

y = \frac{1}{2} x - 1

asymptotes of f(x)=csc(x)asymptotes

f (x) = csc (x)

(- 6.8) (4)

domain of f(x)=(x+1)/(x^2-5x+6)domain

f (x) = \frac{x + 1}{x ^{2} - 5 x + 6}
