What is the Cartesian form of #(81,(17pi)/12)#?

Answer 1

Aurora Alvarado

(-20.96 , -78.24 )

Using the formulae that links Polar to Cartesian coordinates.

#• x = rcostheta #

#• y = rsintheta #

here r = 81 and #theta = (17pi)/12 #

#rArr x = 81cos((17pi)/12) = - 20.96#

and #y = 81sin((17pi)/12) = - 78.24#

The Cartesian form of the point (81, (17π)/12) is (81 cos((17π)/12), 81 sin((17π)/12)), which simplifies to (-40.5√3, 40.5). Therefore, the Cartesian form is (-40.5√3, 40.5).

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.
