Use basic trigonometric identities to simplify the expression: sin (-x) cos (-x) csc (-x) =?

Anestetic [448]

Answer:

$sin (-x) cos (-x) csc (-x) =cos(x)$

Step-by-step explanation:

We know by definition that the cosine is an even function, therefore

$cos (-x) = cos (x)$

We also know that the sin is an odd function, therefore

$sin (-x) = -sin (x)$

By definition:

$cscx = \frac{1}{sinx}.$

Then:

$csc(-x) = \frac{1}{sin(-x)}.$

$csc(-x) = -\frac{1}{sin(x)}.$

Using these trigonometric properties we can simplify the expression

$sin (-x) cos (-x) csc (-x)= -sin(x)cos(x)*(-\frac{1}{sin(x)})\\\\sin (-x) cos (-x) csc (-x)=cos(x)$
