Question

Nasty calculus question :( - Tangents

Answer 1

heheh
tis simpler if you post specifics, thus we all can see if we can help =)

Answer 2

The diagram below shows part of a curve crossing the x-axis at the origin O and at the point a(8,0). Tangents to the curve at 0 and A meet at the point P, as shown


The curve as the equation \[y=12x-3x^{5/3}\]

Answer 3

Find the value of dy/dx at the point 0 and hence write down an equation to the tangent at 0

Answer 4

(ii) Show that the equation of the tangent at A(8,0) is \[y+8x=64\]

Answer 5

"Find the value of dy/dx"

what do you get here?

Answer 6

For dy/dx I got \[12-4x^4 \]

Answer 7

idk how you got 4x^4

Answer 8

that part is incorrect

Answer 9

I didn't think it was right myself!
