solvefor x,3sin^2(x)=cos^2(x)

solve for

x, 3 sin^{2} (x) = cos^{2} (x)

x = \frac{5 π}{6} + πn, x = \frac{π}{6} + πn

Solution steps

3 sin^{2} (x) = cos^{2} (x)

Subtract

cos^{2} (x)

from both sides

3 sin^{2} (x) - cos^{2} (x) = 0

Factor

3 sin^{2} (x) - cos^{2} (x) : (3 sin (x) + cos (x)) (3 sin (x) - cos (x))

(3 sin (x) + cos (x)) (3 sin (x) - cos (x)) = 0

Solving each part separately

3 sin (x) + cos (x) = 0 or 3 sin (x) - cos (x) = 0

3 sin (x) + cos (x) = 0 : x = \frac{5 π}{6} + πn

3 sin (x) - cos (x) = 0 : x = \frac{π}{6} + πn

Combine all the solutions

x = \frac{5 π}{6} + πn, x = \frac{π}{6} + πn

cos (4 0^{\circ})

2 sin (2 x) = sin (x)

sin (\frac{11 π}{4})

arccos (\frac{4}{5})

cos (θ) = 1
