Read the proof.

A 2-column table with 3 rows. Column 1 has entries 1, 2, 3. Column 2 is labeled Step with entries sine (2 x) = sine (x + x), question mark, sine (2 x) = 2 sine (x) cosine (x).

What is step 2?

A. sin(2x) = cos(x)cos(x) – sin(x)sin(x)
B. sin(2x) = sin(x)cos(x) – sin(x)cos(x)
C. sin(2x) = cos(x)cos(x) + sin(x)sin(x)
D. sin(2x) = sin(x)cos(x) + sin(x)cos(x)

Respuesta :

Answer:

D

Step-by-step explanation:

The answer is D on Edge 2020

The missing step in the table is  sin(2x) = sin(x)cos(x) + sin(x)cos(x), the correct option is D.

What is a Trigonometric Ratios?

Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.

The step 1 in the table is

sin (2x) = sin (x+x)

The step 3 is

sin (2x) = 2 sine (x) cosine (x)

The step 2 is obtained by the trigonometric identity

sin (x+y) = sinx cosy + cosx siny

So,

sin (x+x) = sinxcosx+sinx cosx

sin (2x) =  sin(x)cos(x) + sin(x)cos(x)
