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