#sqrt409 /_8,53^@#
Any point #(x,y)# in rectangular form may be converted into polar form #(r, theta)# as follows
#r=sqrt(x^2+y^2)#
#theta=tan^(-1)(y/x)#
Where #theta# is always measured anti-clockwise from the positive x-axis.
So in this case, #r=sqrt(20^2+3^2)=sqrt409#
#theta=tan^(-1)(3/20)=8,53^@#
How do you convert the Cartesian coordinates (20,3) to polar coordinates?
How do you convert polar coordinates to Cartesian coordinates? And vise versa.
