Question

Use the unit circle to find the value of csc (90°)

Answer 1

`\csc(90 \degree)}=1`

Explanation:

We want to find the value of
`\csc(90\degree)`.

Recall from the reciprocals of trigonometric ratios that;

`\csc(90\degree)=(1)/(\sin 90\degree)`

On the unit circle,
`\sin(90\degree)=1`

This implies that;

`\csc(90\degree)=(1)/(1)=1`
