    see if you can think of a function whose derivative is \(\sec(x)\tan(x)\)

    if you take the derivative of \(\sec(4x)\) you will get \(4\sec(4x)\tan(4x)\) which is not at all what you want. just leave the constant alone and take \(4\sec(x)\)

    plug in \(\frac{\pi}{3}\) plug in \(0\) and subtract actually forget 0 because \(\tan(0)=0\)
