Q
How to convert into cartesian form for trig functions
A
- for trigonometric functions use identities to find an expression in terms of theater
- substitute the expression in to the second equation
- simplify
If it asks to state the domain that is the highlighted bit (what y = )

Q
How do you find the gradient for a parametric question
A
the question will ask you to find dy/dx in terms of t
> so you do dx/dt
> dy/dt
then divide dy/dt by dx/dt
> to then get dy/dx
