C4: Parametric Equations
- A parametric equation
is written in the form
x=4t+2, y=t-6. Working
out x and y with the
same value of t.
- In order to change a
parametric equation into a
carteasian equation (in
format: y=mx+c in a sense)
you have to make t the subject
in the x equation and then
substitute it into the y
equation.
- When finding the point
of intersection between a
parametric equation and
a carteasian equation
you need to replace the x
and y in the carteasian
equation with the
corresponding
parametric equation.
