Solve the equation: sin(2x)= sin x

Mathematics
1 answer:
Anna [14]3 years ago
3 0

Answer:

Below

Step-by-step explanation:

sin(2x) = 2 ×cos(x)× sin(x)

● sin(x) = 2 × cos(x) × sin(x)

● 2 × cos(x) = 1

● cos (x) = 1/2

So we can deduce that:

● x = Pi/3 + 2*k*Pi

● or x = -Pi/3 + 2*k*Pi

K is an integer

I have to find the slope for 4. ASAP please help
Lorico [155]

Given:

The objective is to find the slope of the straight line.

Explanation:

The general equation to find the slope is,

m=\frac{y_2-y_1}{x_2-x_1}

Let's consider two coordinates from the graph.

\begin{gathered} (x_1,y_1)=(0,0) \\ (x_2,y_2)=(-1,5) \end{gathered}

On plugging the values in the equation of slope,

\begin{gathered} m=\frac{5-0}{-1-0} \\ m=-5 \end{gathered}

Hence, the slope of the straight line is -5.
