Best ResponseYou've already chosen the best response.2So you mean\[\frac{ d }{ dx }(\tan3x4x)*\frac{ d }{ dx }(3x)*\frac{ d }{ dx }(4x)\]?

Best ResponseYou've already chosen the best response.2And what part of the equation is inside the tan? Is it tan(3x)4x or tan(3x4x)

Best ResponseYou've already chosen the best response.0No 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

Best ResponseYou've already chosen the best response.2Oh, 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\[\frac{ d }{ dx }(\tan3x\csc4x)=3\sec^2(3x)+4\cot(4x)\csc(4x)\]

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

Best ResponseYou've already chosen the best response.0Okay 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

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

Best ResponseYou've already chosen the best response.2ALright, 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 :)
