find the derivative of the function f(x) = e^(3x) sec (7x)

It looks like you just need product rule. Start with the e^(3x). Keep it like that the multiply by the derivative of that sec function which is then sec(7x)tan(7x) . Next add the derivative of the e^(3x) times the regular function from the sec function. So step two is +3e^(3x) times sec(7x)
