Exercise
$\sin2\left(x\right)+\sin\left(x\right)+4\cos\left(x\right)=-2$
Step-by-step Solution
Learn how to solve addition of numbers problems step by step online. Solve the trigonometric equation sin(2x)+sin(x)4cos(x)=-2. Move everything to the left hand side of the equation. Using the sine double-angle identity: \sin\left(2\theta\right)=2\sin\left(\theta\right)\cos\left(\theta\right). Factor 2\sin\left(x\right)\cos\left(x\right)+\sin\left(x\right)+4\cos\left(x\right)+2 by the greatest common divisor 2. Factoring by \sin\left(x\right)+2.
Solve the trigonometric equation sin(2x)+sin(x)4cos(x)=-2
