Trigonometry
Solve the following equation for x if x lies in the interval [−5,π−5]\left[-5,\pi-5\right\rbrack[−5,π−5] .
y=cos(x+5)y=\cos\left(x+5\right)y=cos(x+5)
x=cos−1y+5x=\cos^{-1}y+5x=cos−1y+5
x=cos−1(y+5)x=\cos^{-1}\left(y+5\right)x=cos−1(y+5)
x=cos−1y5x=\cos^{-1}\frac{y}{5}x=cos−15y
x=cos−1y−5x=\cos^{-1}y-5x=cos−1y−5
