Jaweria 2 years ago Need Help badly!!! Find dy/dx: 4x^2+3xy^2-6x^2y=y^3.

1. geerky42

Take derivative of both sides then divide both sides by 3y². Can you handle it? No?

2. Jaweria

if you dont mind can you please go through this problem till its answer because they are really tough examples for me and I am still learning.

3. Jaweria

4. geerky42

OK, Do you know that derivative is distributive? Just take derivative of each term separably.

5. Jaweria

hmm like this?

6. Jaweria

nobody wants to help me out here :(

I think what he is trying to say is look at it this way dy/dx: (dy/dx 4x^2+ dy/dx 3xy^2- dy/dx 6x^2y=y^3. but I too am still learning this junk and its fairly new to me. I do know you have to use the sum laws (i think)

8. geerky42

Ok, I will go through with you. What is derivative of 4x²?

9. Jaweria

its 8x

10. geerky42

Yes, now, what is derivative of 3xy² in respect of x?

11. Jaweria

isnt it 6xy?

12. geerky42

Hmm, no. Try use product rule.

13. Jaweria

ok
