Deal with math questions

For many people, math can be a difficult and challenging subject. However, with practice and perseverance, it is possible to improve one's math skills.

Determine math

To determine what the math problem is, you will need to take a close look at the information given and use your problem-solving skills. Once you have determined what the problem is, you can begin to work on finding the solution.

The surface area of the whole solid is then approximately, S ≈ n ∑ i=12πf (x∗ i)√1+[f ′(x∗ i)]2 Δx S ≈ ∑ i = 1 n 2 π f ( x i ∗) 1 + [ f ′ ( x i ∗)] 2 Δ x and we can get the exact surface area by taking the limit as n n goes to infinity.
