Question 70002
Using the formula for converting from polar to Cartesian coordinates (regular x and y)
{{{x=r*cos(theta)}}}
{{{y=r*sin(theta)}}}
This can be seen if you look at a unit circle.
So {{{x=(15)(cos(2.75))}}}note: check if you are in radian mode on your calculator
{{{x=(15)(-.9243)}}}
{{{x=-13.86453}}}
and
{{{y=(15)(sin(2.75))}}}
{{{y=(15)(0.38166)}}}
{{{y=5.72491}}}of course both of these answers are approximate
