acos(x)=cos(x)

a cos (x) = cos (x)

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

Solution steps

a cos (x) = cos (x)

Solve by substitution

cos (x) = 0

cos (x) = 0 : x = \frac{π}{2} + 2 πn, x = \frac{3 π}{2} + 2 πn

Combine all the solutions

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

4674.04 = \frac{5}{3 cos ( x )} \cdot 2804.42

sin (A) + 3 cos (A) = 0

x, 3 cot (x) - 1 = 0

- sin (x) = 3 cos (x)

cos (2 θ) = sin (θ), 0 \leq θ < 2 π
