So you mean\[\frac{ d }{ dx }(\tan3x4x)*\frac{ d }{ dx }(3x)*\frac{ d }{ dx }(4x)\]?

onegirlBest ResponseYou've already chosen the best response.0
no the derivative of tan 3x  4x...the multiplying part is the directions

That's the answer you got or the correct answer?

And what part of the equation is inside the tan? Is it tan(3x)4x or tan(3x4x)
 one year ago

onegirlBest ResponseYou've already chosen the best response.0
No not the correct answer i need to find the derivative of that and it says to multiply the derivatives of 3x and 4x into the promblem

its tan 3x  csc 4x thats how it written

yes. i think Twis7ed will guide you well.

Oh, ok, so\[\frac{ d }{ dx }(\tan 3x  \csc 4x)=\frac{ d }{ dx }\tan3x  \frac{ d }{ dx }\csc4x\] From that you know that \[\frac{ d }{ dx }\tan3x = 3\sec^2(3x)\] and that \[\frac{ d }{ dx }\csc4x=4\cot(4x)\csc(4x)\]so you end up with\[\frac{ d }{ dx }(\tan3x\csc4x)=3\sec^2(3x)+4\cot(4x)\csc(4x)\]

^Do you understand that?
 one year ago

onegirlBest ResponseYou've already chosen the best response.0
yes, so i dont have to multiply the derivatives of 3x and 4x into the whole problem?

onegirlBest ResponseYou've already chosen the best response.0
yes i understood what you wrote/

Twis7edBest ResponseYou've already chosen the best response.2
I'm not sure, what is the entire question?

onegirlBest ResponseYou've already chosen the best response.0
Okay so I found the derivative of that and my teacher told me to multiply 3x and 4x into it here is how i did it hold on

onegirlBest ResponseYou've already chosen the best response.0
d/dx (tan(3)x  csc 4x = tan(3)  csc 4

i think i understnad where i went wrong now after seeing what you showed

ALright, just try to remember that when you have a trig function you usually use the chain rule with the function and then the function inside of it and it should be easy :)
