Convert theta = pi/4 to rectangular equation

Answers

Answered by Damon
you need both a radius and an angle to convert from polar to x,y coordinates

x = r cos theta
y = r sin theta

if you mean radius of 1 (unit vector
then
x = 1 cos pi/4
y = 1 sin pi/4

since cos pi/4 = sin pi/4 = sqrt 2 /2
x = 1 sqrt 2 /2
and
y = sqrt 2 /2
