Check these please.

Consider 'x' to be a variable. What is the derivative of 12x^4 + 10x^3 - 5x^2 + 16 with respect to x?
48x^3 + 30x^2 - 10x


Consider 'x' to be a variable. What is the integral of 18x^2 - 10x + 3 with respect to x? Pick the most correct solution.

6x^3 - 5x^2 + 3x + C


Suppose the integral was already performed on an equation. What is the simplified answer if you now take the integral from 0 to 1 for the following integrated equation:
8x^3 + 3x^2 - 4x + C
(Hint: closed interval [a=0, b=1])

Hi;

Yep, very good!


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
