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 :

$\frac{\sqrt[]{2}}{2}\div(-\frac{\sqrt[]{2}}{2})=-1$

The answer is -1
