What is the Cartesian form of #(10,(-7pi)/3))#?

Answer 1

#x=5#
#y=-5sqrt3#

The given data #(r, theta)=(10, (-7pi)/3)#

#x=r cos theta=10*cos ((-7pi)/3)=10*cos (-pi/3)=10*(1/2)# #x=5# #y=r sin theta+10*sin ((-7pi)/3)=10*sin (-pi/3)=10((-sqrt3)/2)# #y=-5sqrt3#

God bless....I hope the explanation is useful.

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.
