Question

Can someone explain when in calculus, you need to complete anti-derivatives and when you need to use the table of integrals or you just need to differentiate the problem

Answer 1

its easier to differentiate, and that depands on your qustion. type it all

Answer 2

one question is xsqrt of (x+2) dx, well i know i can try and solve this via substitution rule, but there is also a rule in the table of integrals that can solve this as well. how do i know which way to go? another question is 1/sqrt 1-9x^2, this i can also use substitution but there is a rule as well, is there something in the equation i should look to help me make the decision?

Answer 3

mmm I told u using differentiate is better since u will get used to it, how ever when its a squre that a hints to use substitution, other wise cos ,sin use rule ,but u have to remember that any way or role leads to a correct answer is true , use wat use the esiest for u

Answer 4

oh ok but when i differentiate and then use the table, i get a different answer but i guess it makes sense to use the table if my differentiation looks messy
