# How do you convert #(2, 3pi/4)# into cartesian form?

##### 1 Answer

#### Explanation:

Currently the coordinate

We could use a funky looking graph like this in order to plot that point.

However, if we want to convert the coordinate into a more familiar rectangular or cartesian form, we need to get the coordinate into

we can use the formula

to get the number into

This is because

Plugging in for r and theta, in radians, we get

If we were to graph the point, we would do something like this, but instead of 2, we would plot the x axis at
