inverse of cos(pix-2)-1

Solution

inverse

cos (π x - 2) - 1

Solution

\frac{arccos ( x + 1 ) + 2}{π}

Solution steps

Solve for

cos (π x - 2), y = cos (π x - 2) - 1

cos (π x - 2) = y + 1

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

π x - 2 = arccos (y + 1)

Solve for

x, π x - 2 = arccos (y + 1)

\frac{arccos ( y + 1 ) + 2}{π}

Substitute

y = x

\frac{arccos ( x + 1 ) + 2}{π}
