Mathematics 133 -- Intensive Calculus for Science 1
Quiz 8
November 8, 2005
The eighth regular quiz of the semester will be given in class on
Friday, November 11. It will cover the material from sections
3.5, 3.6, and 4.1 from this week's problem set. You
may use a calculator on this quiz. The specific topics
to be covered will be:
- Additional ``shortcut rules'' for computing derivatives of
functions involving trig functions, natural logarithms, and inverse trig functions:
- d/dx(sin(x)) = cos(x) and d/dx(cos(x)) = -sin(x)
- d/dx(ln(u)) = 1/u du/dx
- d/dx(arcsin(u)) = 1/sqrt(1 - u2) du/dx
- d/dx(arctan(u)) = 1/(1 + u2) du/dx
- Critical points, local maxima and minima, and the first
and second derivative tests for classifying critical points.
You will need to be able to use the derivative rules above
in conjunction with our other shortcut rules:
- The product rule: d/dx(f(x)g(x)) = f(x)g'(x) + g(x)f'(x)
- The quotient rule:
d/dx(f(x)/g(x)) = (g(x)f'(x) - f(x)g'(x))/(g(x))2
- The chain rule: d/dx(f(g(x)) = f'(g(x)) g'(x)
On the quiz, there will be two or three
questions similar to problems from the assignment.
Good Review Problems
- Problems like Chapter 3 Review/1 - 66 (you should be able to
find the derivative of all these now)
- Problems like Section 4.1/13 - 20 (derivatives and algebra first)
