3-4cos(A)=1

3 - 4 cos (A) = 1

A = \frac{π}{3} + 2 πn, A = \frac{5 π}{3} + 2 πn

Solution steps

3 - 4 cos (A) = 1

Move

3

to the right side

- 4 cos (A) = - 2

Divide both sides by

- 4

cos (A) = \frac{1}{2}

General solutions for

cos (A) = \frac{1}{2}

A = \frac{π}{3} + 2 πn, A = \frac{5 π}{3} + 2 πn

3 tan (x) - 2 cos (x) = 0

sin (a) = - \frac{3}{5}

cot (x) = cot (3 x - 50)

sinh (x) = - 6

tan (θ) = \frac{2}{2}
