AboutScotto 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.
Expert: Scotto Date: 6/16/2008 Subject: Arc Length of Sine Curve
Question A particle moves at a constant speed of v m/s along a sinusoidal path. The path is described as
y = a*sin(bx)
I want to find expressions for the x and y coordinates as a function of time (t).
Given that at t=0, x=0, y=0.
Answer To find the arc length of a curve, the equation must be solved from 0 to a using the integral (0 to a)(1+(f'(x))^2)^0.5.
