Hi, I'm having a terribly difficult time deciphering whether an improper integral is divergent or convergent. From what I notice, is it divergent whenever the answer is infinity? and convergent whenever the answer equals a specific number? I just got an answer that is: the limit as a approaches nega...

Hi, I'm doing integration by substitution using u....I'm noticing that some of the answers show brackets and others show parenthesis when I'm taking the antiderivative of ln. For example, parenthesis were involved in answers such as 1/2ln(.3x^2-.4x+2) + c ln(1+e^x) + c wheras absolute value bars wer...

Hi, I need helping finding the derivative of a exponential natural log with a constant in front. An example will explain my assistance much better. For example: g(x)=2e^x would the answer be just that, g'(x)= 2e^x, due to the constant being in front of e^x and the fact that the derivative of e^x is ...

Find the derivative of the function: f(x)= 3(x^5 + x)^6 would the answer to that problem be 18(x^5 + x)^5? No. You have differentiated the outer process, being the "raised to the sixth power". You now need to differentiate the inner process, being the polynomial. In other words, you need to apply t...

Hi, I know the following question isn't too difficult; I just need some clarification. Find the derivative of the function: f(x)= 3(x^5 + x)^6 would the answer to that problem be 18(x^5 + x)^5? whereas if the problem were f(x)=3x(x^5 +x)^6 you would have to use the product rule followed by the chain...
