7cos(x)+12=6cos(x)+13

7 cos (x) + 12 = 6 cos (x) + 13

x = 2 πn

Solution steps

7 cos (x) + 12 = 6 cos (x) + 13

Solve by substitution

cos (x) = 1

cos (x) = 1 : x = 2 πn

Combine all the solutions

x = 2 πn

sin (\frac{x}{2}) + cos (\frac{x}{2}) = 2

cos (θ) = - \frac{1}{2}, 0 \leq θ < 2 π

2 tan (x) - 16 = 0, 0 \leq x < \frac{π}{2}

x, sin (x) = \frac{2}{2}

4 sec (x) + 6 = - 2
