4sin(x)+1=-2

4 sin (x^{\circ}) + 1 = - 2

No Solution for x \in R

Solution steps

4 sin (x^{\circ}) + 1 = - 2

Move

1

to the right side

4 sin (x^{\circ}) = - 3

Divide both sides by

4

sin (x^{\circ}) = - \frac{3}{4}

Apply trig inverse properties

x^{\circ} = arcsin (- \frac{3}{4}) + 2 πn, x^{\circ} = π + arcsin (\frac{3}{4}) + 2 πn

No Solution for x \in R

(2 cos (x) + 1) (3 tan (x) - 1) = 0

α, cos^{2} (α) + cos^{2} (β) = 1

sin^{2} (x) - cos (x) tan (x) = 0

sin (x + 3 0^{\circ}) = \frac{1}{2}

sin (θ) = 21
