4 0

Answer:

Simplify the numerator with the sine expression by taking A = B = x and simplify the denominator using A = x and B = 2x. The resulting denominator will have sin (2x) and cos (2x) which you can write in terms of sin (x) and cos (x) using the expressions above.

The sine increases from 0 to 90 degrees and from 270 to 360 degrees
The sine decreases from 90 to 270 degrees

The cosine increases from 180 to 360 degrees
The cosine decreases from 0 to 180 degrees

Sine = 0 at 0 and 180 degrees

Cosine = 0 at 90 and 270 degrees

What is 2 and negative three using integers

Darina [25.2K]

If you mean "how to write the sum", the answer is

$2+(-3)$

The result of this sum is $-1$ , because you start from 2 on the number line and take 3 steps to the left (negative integers mean going left, positive integers mean going right)
