This problem is making me dizzy. I would greatly appreciate a little help!
Express the derivative dy/dx in terms of x. y=u^2(uu^4)^3 and u=1/x^2
Truly,
Hi Jennifer, Since y is a function of u and u is a finction of x you can find dy/du and du/dx. To find dy/dx you need to string them together using the chain rule which states that
This gives you dy/dx in terms of x and u but you know that u=1/x^{2} so substitute for u and then you have dy/dx in term of x alone.
cheers,
