What is the Cartesian form of #( 15 , ( 7pi)/3 ) #?

Answer 1

#(15/2,15sqrt3/2)#

In Polar coordinates a point is represented as #P (r,theta)# In Cartesian form it is represented as #P (x,y)# Where #x=rcostheta# And #y=rsintheta# #:.# Cartesian form of #P (15,(7pi)/3)# will be #x=15xxcos ((7pi)/3) =15/2# #y=15xxsin ((7pi)/3) =15sqrt3/2# #:.# The point in Cartesian coordinate will be #P (15/2,15sqrt3/2)#
