2cos(a)+3=4

2 cos (a) + 3 = 4

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

Solution steps

2 cos (a) + 3 = 4

Move

3

to the right side

2 cos (a) = 1

Divide both sides by

2

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

tan (x) cot (x) - 3 tan (x) = 0

cos (θ) = 0.139

- \frac{2 3}{3} = sec (θ)

1 sin (3 0^{\circ}) = 1.7 sin (θ)

sin (x) = \pm \frac{1}{2}
