I'm revising differentiation for tomorrow, I am hopelessly stuck on some things.
I have some examples with answers, but I have no idea which rules are being used.
y=2sin3x dy/dx=6cos3x
I see that sin goes to cos but why is the two multiplied by the 3 (if that's what's happening)?
y=3sin1/2x+e^x dy/dx= 6cos1/2x+e^x
Thank you
