What is the Cartesian form of #(4,(23pi )/12)#?

Answer 1

#(x,y) -> (sqrt(6) +sqrt(2) , sqrt(2) - sqrt(6) ) #

As seen in the image, we see that the #x# coordinate is #rcostheta #, and the #y# is #rsintheta # obtained by simple trig

#r = 4 , theta = (23pi)/12 #

#=> x = 4cos( (23pi)/12 ) = sqrt(6) + sqrt(2) #

#=> y = 4sin( (23pi) / 12 ) = sqrt(2) - sqrt(6) #

#(r, theta ) -> (4, (23pi)/12 ) #

#color(blue)((x,y) -> (sqrt(6) +sqrt(2) , sqrt(2) - sqrt(6) ) #

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.
