c4 cartesian equations
How do I go about writing a cartesian equation with
x= sin^2 theta
y= 1 + 2sin theta
any tips would be much appreciated
x= sin^2 theta
y= 1 + 2sin theta
any tips would be much appreciated
Rearrange the 2nd equation into the form Sin(Theta) = [(y-1)/2] then substitue into x=Sin^2(Theta) 
thanks -- I've got it now
