Question

Calculus problem?

Answer 1

\[3x +x \tan x\] Find dy/dx

Answer 2

did you attempt?

Answer 3

hint , you will need to use product rule

Answer 4

yep, it's product rule
3x + (1) (tanx) + sec^2x(x)

Answer 5

that's my first step

Answer 6

a minor error
instead of having 3x + (1) (tanx) + sec^2x(x)

you should have 3+tanx+ (x)*(sec^2x)

Answer 7

how is that? can you show me step by step?

Answer 8

sure,

Answer 9

hmm i never done it with d/dx before...

Answer 10

so the format seems unfamiliar... sorry

Answer 11

no worries you can use the prime ' NOTATION instead of writing d/dx

Answer 12

in simple terms, we find derivative of 3x which is 3
derivative of xtanx which is 1*tanx + x * sec^2x

Answer 13

Oooohh i forgot to take the derivative of 3! ok i get it now
