solvefor x,arccos(x)= 1/2

solve for

x, arccos (x) = \frac{1}{2}

x = cos (\frac{1}{2})

Solution steps

arccos (x) = \frac{1}{2}

Apply trig inverse properties

arccos (x) = \frac{1}{2}

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

x = cos (\frac{1}{2})

x = cos (\frac{1}{2})

cos (2 x) = \frac{1}{5}

sin^{2} (θ) - \frac{1}{2} = 0

sin (x) - sin (x) tan (x) = 0

tan (θ) = \frac{2}{10}

sin^{2} (θ) = - 1
