Question
Eliminate the parameter 0 in the following parametric equations. (This curve is called a hyperbola.)
x = a cot(0)
y = b csc(0)
First,
x = a cot(0)
y = b csc(0)
= cot(0)
= csc(e)
and
cot2(0)
csc2(e)
=
Using a Pythagorean Identity, we see that
cot2(0) =
csc2(0) – 1
x2
- 1
a2
= 1,
which is the equation of a hyperbola.
