Question

Use the value of the trigonometric function to evaluate the indicated function.

sin(–t) = 5/6
Find sin(t).

Answer 1

`\displaystyle \sin t = - (5)/(6)`

Explanation:

Recall that since sine is an odd function:

`\displaystyle \sin (-\theta) = -\sin \theta`

Hence:

`\displaystyle \sin(-t) = -\sin t = (5)/(6)`

Therefore:

`\displaystyle \sin t = - (5)/(6)`
