can you show me how to solve an equation using the chain rule

Answer 1

let y= rqt^3.5 where r, q, t are functions of x

then chain rule is....

y'= dr/dx * qt^3.6 + rt^3.5 *dq/dt + rq dt^3.5/dx

y'= dr/dx * qt^3.6 + rt^3.5 *dq/dt + 3.5rqt^2.5 * dt/dx

that is the chain rule.

Answer 2

so, why toss in the product rule as well?
