igcse maths?...

@d!_†oX!©:
u need to draw a tangent at the point x=2 on the graph....
and then find the gradient by y2-y1/x2-x1

see the graph here....now just take out the gradient
no need for differentiation!!

lol:
Yep IGCSE 0580 Maths Paper 4 June 2009

Yea I could do it that way, but I just want to check using differentiation because i'm going to need to be able to do that way later. Also sometimes my tangents aren't very accurate so I just want to be able to use differentiation to check it.

Thanks
