solvefor x,z=tan(x/2)

solve for

x, z = tan (\frac{x}{2})

x = 2 arctan (z) + 2 πn

Solution steps

z = tan (\frac{x}{2})

Switch sides

tan (\frac{x}{2}) = z

Apply trig inverse properties

\frac{x}{2} = arctan (z) + πn

Solve

\frac{x}{2} = arctan (z) + πn : x = 2 arctan (z) + 2 πn

x = 2 arctan (z) + 2 πn

tan (\frac{x}{2}) = 3, 0 \leq x \leq 2 π

0 = 4 sin (2 θ)

tan (θ) + 3 = 0

cos (2 x) - 4 cos (x) + 3 = 0

6 cos^{2} (A) - 5 cos (A) + 1 = 0
