<p>hey ive been searching online for the answers to these three AP calc BC packets i have. ill state the first question for each of them so that you can find them easier (hopefully)</p>

<p>1st packet: 1. if y = sin^3x, then dy/dx =</p>

<p>2nd packet: 1. if f(x) = 3x-2/2x+3, then f'(x)=</p>

<p>3rd packet: If y = sin (3x), then dy/dx =</p>
