is anyone on this board competent in calculus ?

(1/6) > >>

coola:
i need help in a differentiation question... if you could show working, that'd be superb... cheers.

1.)   (2y - x)^4 + x^2 = y + 3

2.)  2(x^2 + 1)^3 + (y^2 + 1)^2 = 17

Kassem:
wat does the whole q say

Digital Pimpin':
Damn you're gonna have to use implicit differentiation for this. I would help out but it's been years since I did this, and I would need the weekend to school up.

The only hint I can give you is that both answers will be expressed in terms of x and y, not just x as regular differentiation usually gives you.

Good luck.

coola:
this is the question: find dy/dx by differentiating implicitly. when applicable, express the result in terms of x and y ...

i just goto find dy/dx dont need to solve for x and y on this one...

dammet ! the problem is i never did calculus in high school, i'm learning all this shit myself from the text book... so i have a few gaps in fundamental rules of calculus..  >:(

Kassem:
1st one   

4(2y-x)^3 - 2x / 8(2y-x)^3 - 1 = dy/dx
