Question 1138309

 
To convert from Polar Coordinates ({{{r}}},{{{theta}}}) to Cartesian Coordinates ({{{x}}},{{{y}}}) :

{{{x = r * cos( theta )}}}
{{{y = r * sin( theta)}}}

{{{r=-5}}}
{{{theta=5pi/3}}}

{{{x = -5* cos( 5pi/3 )}}}

{{{x = -5*(1/2)}}}

{{{x = -5/2}}}

{{{y = -5* sin( 5pi/3)}}}

{{{y = -5* ( -sqrt(3)/2)}}}

{{{y = 5sqrt(3)/2)}}}



({{{x}}},{{{y}}}) =({{{-5/2}}},{{{5sqrt(3)/2)}}})
