What is the Cartesian form of #( -12 , (13pi)/3 ) #?

Answer 1

Cameron Alexander

The Cartesian form is: #(-6,-6sqrt3)#

Use the conversion equations:

#x = rcos(theta)# and #y = rsin(theta)#

#x = -12cos((13pi)/3)# and #y = -12sin((13pi)/3)#

#x = -6# and #y = -6sqrt3#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
