Can someone please help me find the derivative of the following $\displaystyle h(t)=s^2t+s $
I've tried it, but I always get the wrong answer, I get $\displaystyle h'(t)=s^2+s $
Thank you!
Ok, but I thought, that since h is a function of t, I should only derivate t, and since t becomes 1, then s remains.
I am guessing, because I usually get it wrong, and I am not sure about it(though I am sure that the derivative of a constant is zero).
But thank you so much!
