inverse of y=cos(x-pi/2)

Solution

inverse

y = cos (x - \frac{π}{2})

Solution

arccos (x) + \frac{π}{2}

Solution steps

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

x - \frac{π}{2} = arccos (y)

Solve for

x, x - \frac{π}{2} = arccos (y)

arccos (y) + \frac{π}{2}

Substitute

y = x

arccos (x) + \frac{π}{2}
