Homework Statement
Finding the equations of common tangents of [itex]y^{2}[/itex]=4ax and [itex]x^{2}[/itex]=4by
Homework Equations
Equating both curves' derivatives :
[itex]\frac{2a}{y}[/itex]=[itex]\frac{x}{2b}[/itex]
The Attempt at a Solution
Calculated both of the curves' derivatives and equated them .
Used the resulting relation in two point form of straight line equation (y-y1)=m(x-x1) .
Got Stuck now! with too many cuberoots .
