Best ResponseYou've already chosen the best response.0I'm a little confused, where do i know to put d/dx and when to directly do the derivative..

Best ResponseYou've already chosen the best response.0i did, but thats where im confused... it's like i can take the derivative of 3x^2 but then should i put d/dx next to it... or just simply leave it 6x

Best ResponseYou've already chosen the best response.0then also 3xy... derivative or not... i know i have to put d/dx

Best ResponseYou've already chosen the best response.0if it's a function of x then take the derivative of the function and multiply by its differential, dx. Same with y. example. for x^2 you'd get 2x*dx, for y^2 you'd get 2y*dy

Best ResponseYou've already chosen the best response.0for xy, use the product rule. y*dx + x*dy

Best ResponseYou've already chosen the best response.0right, okay. let me try again

Best ResponseYou've already chosen the best response.0so first it would be 6x*d/dx right?

Best ResponseYou've already chosen the best response.0and what about the 3 do i leave it out? and use product rule with xy?

Best ResponseYou've already chosen the best response.03 is a constant so it oges along for the ride. also, d/dx is an operator. it says to take the derivative of whatever follows wrt x.

Best ResponseYou've already chosen the best response.0i dont know ive been using d/dx whenever i see an x and dy/dx for a y

Best ResponseYou've already chosen the best response.0dx is the differential of x... the change in x, if you will

Best ResponseYou've already chosen the best response.0you could do dx/dx everytime you take a derivative of a function of x and dy/dx for a function of y... that's okay. but dx/dx is just 1.

Best ResponseYou've already chosen the best response.0for the middle part, is it, 3x*dx/dx+y*dy/dy?

Best ResponseYou've already chosen the best response.0i 've got to go... so you can at least check... you should get 3 as the final answer. Good luck!
