picos(pix)=0

π cos (π x) = 0

x = \frac{1}{2} + 2 n, x = \frac{3}{2} + 2 n

Solution steps

π cos (π x) = 0

Divide both sides by

π

cos (π x) = 0

General solutions for

cos (π x) = 0

π x = \frac{π}{2} + 2 πn, π x = \frac{3 π}{2} + 2 πn

Solve

π x = \frac{π}{2} + 2 πn : x = \frac{1}{2} + 2 n

Solve

π x = \frac{3 π}{2} + 2 πn : x = \frac{3}{2} + 2 n

x = \frac{1}{2} + 2 n, x = \frac{3}{2} + 2 n

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

2 tan (x) sin (x) - 2 tan (x) = 0

1 - tan (x) = sec (x)

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

cos (θ) = 1 + sin (θ)
