About Scotto
Expertise
Any kind of mathematics (algebra, geometry, trigonometry, matrices, calculus, linear approximation, linear regression, linear programming, numerical analysis, probability, statistics, etc.). I also have answered some questions in Physics, Chemistry, and Biology. I would like to volunteer in all areas of Mathematics, not just calculus, and the other three courses that were mentioned.
Experience
Experience in the area: I have tutored students in all areas of mathematics for over 20 years.
Education/Credentials: BSand MS in Mathematics from Oregon State University, where I completed sophomore course in Physics and Chemistry. I received both degrees with high honors.
Awards and Honors: I have passed Actuarial tests 100, 110, and 135.

Question
OK I need help. I took this class spring semester at UT austin and failed. So now I am taking it at Austin Comunity College and I made a 20% on the first test. If I make corrections I can raise that to a 40%. Is there anyway I can e-mail you a copy of the test along with my solutions
Answer
As long as there weren't too many questions on the exam, you could type in all of the problems and send them to me. I can give you a few hints:
d(x^n)/dx = nx^(n-1) (it does not matter if x is an integer or fraction; note that x^0.25=0.25x^-0.75);
x=distance, v=velocity, a=acceleration, dx/dt=v, dv/dt=a;
area under a curve between a and b is the integral from a to b of the curve (area under x^2 from 1 to 4 is 4^3/3 - 1^3/3 = 64/3 - 1/3);
the integral of x^n is x^(n+1)/(n+1) + C (the integral of x^5.5 is x^6.5/6.5);
if an integral has limits (a,b), let F(X)=integral(f(x)), and the answer is F(b)-F(a);
maximums and minimums occur when the derivative is 0;
