Question 1

how to convert into cartesian form for non trig funtions

Answer 1

Question 2

How to convert into cartesian form for trig functions

Answer 2

1. for trigonometric functions use identities to find an expression in terms of theater
2. substitute the expression in to the second equation
3. simplify

If it asks to state the domain that is the highlighted bit (what y = )

Question 3

How do you find where a parametrics curve crosses the axes

Answer 3

Question 4

what is the formula for integrating a parametrics equation

Answer 4

Question 5

How do you find the gradient for a parametric question

Answer 5

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
