I'm unsure on the following C4 Coordinate Geometry Question
A curve has the following parametric equations
a) show that
, would this be done using dy/dx = (dy/dt)/(dx/dt)?
b) find an equation for the normal to the curve at point where t = 1
this would just be substituting t=1 into the x, y and dy/dx equations and using (y-y1) = m(x-x1), yeah?
c) show that the cartesian equation of the curve can be written in the form
unsure on this
