Question:

Find a set of polar coordinates for the point with rectangular coordinates (5,5*sqrt(3)).

Veronica A.

Answer:

r^2=x^2+y^2=5^2+(5*sqrt(3))^2 = 25+75 = 100. Therefore, r = 10. tan theta = y/x. Therefore, tan theta = (5*sqrt(3)) / 5 = sqrt (3). Therefore, theta = pi/3 Because r = 10, theta = pi/3, (10, pi/3) is a set of polar coordinates for this point.
