5sin(x)=sqrt(3)+3sin(x)

5 sin (x) = 3 + 3 sin (x)

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

Degrees

x = 6 0^{\circ} + 36 0^{\circ} n, x = 12 0^{\circ} + 36 0^{\circ} n

Solution steps

5 sin (x) = 3 + 3 sin (x)

Solve by substitution

5 sin (x) = 3 + 3 sin (x)

Let:

sin (x) = u

5 u = 3 + 3 u

5 u = 3 + 3 u : u = \frac{3}{2}

5 u = 3 + 3 u

Move

3 u

to the left side

5 u = 3 + 3 u

Subtract

3 u

from both sides

5 u - 3 u = 3 + 3 u - 3 u

Simplify

2 u = 3

2 u = 3

Divide both sides by

2

2 u = 3

Divide both sides by

2

\frac{2 u}{2} = \frac{3}{2}

Simplify

u = \frac{3}{2}

u = \frac{3}{2}

Substitute back

u = sin (x)

sin (x) = \frac{3}{2}

sin (x) = \frac{3}{2}

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

sin (x) = \frac{3}{2}

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

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

Combine all the solutions

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

cos (a) = 0.3

5 + 3 tan (x) = 4

cos (x) + sin (\frac{x}{2}) = 0

4 cos (2 θ) = 8 sin^{2} (θ)

cos (θ) = (\frac{5}{29})
