solvefor x,cos(x)*cos(y)=0

solve for

x, cos (x) \cdot cos (y) = 0

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

Solution steps

cos (x) cos (y) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

cos (x) = 0

General solutions for

cos (x) = 0

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

3 sec (θ) = 6

cot (x) = csc (x) + 3

cos (x) \cdot cos (3 5^{\circ}) = 1 - sin (x) \cdot sin (3 5^{\circ})

sin (3 θ - 15) = 0.7

tan (x - \frac{π}{6}) = 1
