Question

Which shows a correct simplification of sin(x + pi)?

Answer 1

Answer:

sin(x + Pi)

= sin(x)cos(Pi) + cos(x)sin(Pi)

= sin(x) · –1 + cos(x) · 0

= –sin(x)

Answer 2

The simplification of the trigonometric sinusoidal function of sin(x + π) is given as negative of sin x.

What is a sinusoidal Function?

It is a function that repeats itself in a particular time interval.

The expression is given as sin(x + π)

We know that the sine formula is given as

$\sin (A+B) = \sin A \cos B + \cos A \sin B$

Then we have

A = x and B = π

Then the sin (x + π) will be

$\sin (x+\pi) = \sin x \cos \pi + \cos x \sin \pi\\\\\sin (x+\pi) = \sin x \times (-1) + \cos x \times 0\\\\\sin (x + \pi ) = - \sin x$
