solvefor x,sqrt(2)sqrt(2.25)cos(x)=0

solve for

x, 2 \cdot 2.25 \cdot cos (x) = 0

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

Solution steps

2 2.25 cos (x) = 0

Simplify

2 2.25 : 4.5

4.5 cos (x) = 0

Divide both sides by

4.5

cos (x) = 0

General solutions for

cos (x) = 0

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

x, 2 sin (x) = 1

cot (x) + 2 cos (x) = 0

2 cot (θ) - 1 = 2, cot (θ) - 1 = 0

2 cos^{2} (a) - 7 cos (a) + 3 = 0

y, x = 2 cos (2 y)
