solvefor x,cos(x)=y

solve for

x, cos (x) = y

x = arccos (y) + 2 πn, x = - arccos (y) + 2 πn

Solution steps

cos (x) = y

Apply trig inverse properties

cos (x) = y

General solutions for

cos (x) = y

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = - arccos (a) + 2 πn

x = arccos (y) + 2 πn, x = - arccos (y) + 2 πn

x = arccos (y) + 2 πn, x = - arccos (y) + 2 πn

tan (θ) = \frac{48}{90}

cos (θ) - 1 = 2 cos^{2} (θ) - 1

6 sin^{2} (θ) = 3

6 sin^{2} (θ) = 2

10 tan (θ) + 9 = 0
