A hyperbola of the form (x−h)2a2−(y−k)2b2=1 can be parametrically represented as (a secθ+h,btanθ+k)
True
This is the easy way of arriving at the parametric equation.
We are making use of the identity
sec2θ−tan2θ=1
Comparing this with the equation of the given hyperbolas
x−ha=secθ and y−kb=tanθ
x=(a secθ+h) y=btanθ+k
∴ Required parametric form= (asecθ+h,btanθ+k)
