Hi have a question which requires changing polar coordiantes to cartesian for the equation r=exp(titah)
using
r = (sqrt(x^2+y^2)
titah = arctan(y/x)
r = x/cos(titah) = y/sin(titah)
i get this equation
sqrt(x^2+y^2) = exp(arctan(x/y)
ln(sqrt(x^2+y^2)=arctan(x/y)
any help on how to separate the variables? to form an equation y=f(x)
