2cos^3(x)=0

2 cos^{3} (x) = 0

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

Solution steps

2 cos^{3} (x) = 0

Divide both sides by

2

cos (x) = 0

General solutions for

cos (x) = 0

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

50 sin (x) + 15 cos (x) = 40, 0 < x < π

sec^{2} (θ) + sec (θ) = 6

10 sin (x) cos (x) = 6 cos (x)

sin (x) + cos (x) = sec (x)

y, x = tan (y^{2})
