Pure Maths EQ - Parametric Integration, Parametric Differentiation and Equation of Tangent

When working out the area under the curves, could you use the normal Line equation and integrate with the limits with respect to x instead of t?

We haven’t done Parametrics yet but you made it seem so easy 😂

thank you so much

For the last question when you did 9(2)^5/5 how did you get 2592/5? I am asking this because when I did that I got 2187/5. I don't understand how I could be wrong.

[@mohammedthamer9206]

do p and q attain the same gradient

Is there no other way to solve last part cuz that’s so long and hard id think I’ll k how to do that in test can you like not just integrate both then subtract or something

[@photoballa]

How is it long, don’t draw the diagrams and like do it. I mean you could convert to cartesian but there’s no advantage, this is the quickest method

You can draw two triangles. The intersection of line L and the x-axis is at (-9,0) so you can draw a small triangle between (-9,0) and (-4,3) and a big triangle from (-9,0) to (36,27) then add your integration to the small triangle and take it all away from the big triangle
