I can provide good answers to questions dealing in almost all of mathematics especially from A`Level downwards. I believe i would be very helpful in calculus and can as well help a good deal in Physics with most emphasis directed towards mechanics.

I can answer questions from the standard four semester Calculus sequence. I am not prepared for questions on Tensor Calculus. Everything else is welcome. Derivatives, partial derivatives, ordinary differential equations, single and multiple integrals, change of variable, vector integration (Green`s Theorem, Stokes, and Gauss) and applications.

1) Let the length be L and the width be W.  It is known that 2L + 2W = 72.  Dividing by 2 gives [A] L + W = 36.  The area A is [B] A = LW.    Subtracting off L from both sides of [A] gives [C] W = 36 -

1. The population graph over time is increasing since it has a growth rate.  It is concave down since it is decreasing over time.    2. a. Since the graph is only a quadratic, the second derivative is

Hello Victoria,    Let me give you some hints, and then if you need more help let me know.    1. Use integration by parts...letting u=f(x) and dv=g''(x) dx.    2. Use the substitution y=e^(-x^2)...

#### 2017-03-19 choosing a suitable substitution for the integral of 1/(x^2+x+1):

Hi,      You are on the right solution pathway, the integral subsequently gets reduced to an arctan function.    Here is the general formula:    <u>integrating f'(x)/{[f(x)]^2 +a ^2 } wrt x gives 1/a *

#### 2017-03-17 Extrema, Rolle's and Mean Value Theorem:

A) The global or absolute maximum is the highest point the graph reaches in the y direction.    B) The global or absolute minimum is the lowest point the graph reaches in the y direction.    C) The global
