We have that <span> -3r+3u </span> Step 1 <span>Use the distance formula to find the radius </span><span>r = √(x^2 + y^2) (x,y)----------> (</span>-3,3) r= √(-3^2 + 3^2)=√18=3√2
Step 2 Use the tangent to find the angle θ = arctan(y/x) θ = arcTan(3/-3)= -45°-------> II Quadrant then θ=180-45=135°
Step 3 write in polar form (x,y)------------> (r, θ) so (-3,3)----------> (3√2, 135°)
