Question

Use the unit circle tan (3/4)

Answer 1

Using the unit circle, the coordinates of 3π/4 is :

`(-\frac{\sqrt[]{2}}{2},\frac{\sqrt[]{2}}{2})`

Note that tangent function can be solved using the formula y/x

where x and y are the coordinates of the angle.

This will be :

`\frac{\sqrt[]{2}}{2}/(-\frac{\sqrt[]{2}}{2})=-1`

The answer is -1
