Reviews: 9
For the first equation: $$\sin x + \sin 5x = 2\sin\left(\frac{x+5x}{2}\right)\cos\left(\frac{x-5x}{2}\right) = 2\sin(3x)\cos(-2x) = 2\sin(3x)\cos(2x),$$ and thus: $$2\sin(3x)\cos(2x) + \sin 3x = 1.$$

How to solve sin 3x = 0?
Solve sin 3x = 0. There is another way to solve sin 3x = 0. a. sin x = 0 --> x = 0, and x = π, and x = 2π. - When sinx = − √3 2 --> x = − π 3 and x = −2 π 3. We start by taking the inverse sine ( arcsin) of both sides.

What if sin x is 0?
Let us begin with a basic equation, sin x = 0. The principal solution for this case will be x = 0, π, 2π as these values satisfy the given equation lying in the interval [0, 2π]. But, we know that if sin x = 0, then x = 0, π, 2π, π, -2π, -6π, etc. are solutions of the given equation.

What is the limit of SinX/x when x approaches 0?
The limit of sinx/x as x approaches 0 is 1, that is, the limit formula of sinx/x when x tends to 0 is given by lim x→0 sin x x = 1. Let us now prove that the limit of sinx/x is equal to 1 when x goes to 0. x x = 1. Solution: We know that for all real values of x, sin x ≤ x and x ≤ tan x. This implies that sin x ≤ x ≤ tan x
