Question

the rectangular coordinates are given, find polar coordinates in (r,theta) of each point
(-4,4 sqrt3)
a.use the equation r^2=x^2+y^2 to find the radius of the point
b.use the fact that tantheta=y/x, x is not equal to 0 to find the angle (in radians) for this point
b.combine your answer to write polar coordinates of this point

Answer 1

x=-4
y=4
\[r^2=x^2+y^2=16+16=\]

Answer 2

Can you continue from there?

Answer 3

no
