For this problem, I think the issue is really getting it into a form that looks easier to solve. If you just saw 2x, you could probably take the derivative. Or 2x^3 or 2x^4. You just use the power …

## Tutoring Calculus, Fractional Exponents

We went over the homework for a bit, problems with integration. The main issue was more with the negative exponents and some of the algebra involved in the problems. Sometimes in an integration …

## Tutoring Calculus, Optimization Problems

We looked at problems with optimization again. They tend to have a similar form. One variable is to be optimized. There is usually a constraint. The teacher calls these primary and secondary …

## Tutoring Calculus, Optimization and getting away from prime notation for derivatives

We started by looking at finding critical numbers from graphs. To get to a maximum, it is increasing to the left since it needs to go up to the max. To get to a minimum it is descending to the left. …

## Tutoring Calculus, dealing with constants

We mostly looked at the recent test from last week. It had problems with critical numbers. Numbers that lead to vertical asymptotes are also critical numbers. The second derivative was also used a …

## How do we find the derivative of 1/(1+x) ?

I would recommend rewriting the expression first. Sometimes if you change how something looks, it becomes easier to work with. Now you can do the power rule and the chain rule. …
