jim_thompson5910 · Answer

ok, which problem to start with?

marissalovescats · Answer

The beginning lol

I dont remember this like at all lol

jim_thompson5910 · Answer

ok so 1) y = ln(4x) right?

jim_thompson5910 · Answer

for some reason, they say "example" and it makes me think that they are working out that problem (and not the student). It's a bit confusing

marissalovescats · Answer

No it's like the "notes" portion lol

jim_thompson5910 · Answer

but the rule for ln is 

if y = ln(x), then dy/dx = 1/x

this is just something you memorize

marissalovescats · Answer

Yeah that one I know

jim_thompson5910 · Answer

so if y = ln(4x), then dy/dx = ??

jim_thompson5910 · Answer

that "4x" inside will require you to use the chain rule

marissalovescats · Answer

1/4x and derive it? idk

jim_thompson5910 · Answer

you'll have 1/(4x) and then you will multiply by the derivative of the inner stuff

so multiply by the derivative of 4x...which is 4
