"Some general (mostly) conceptual math questions ranging from freshman geometry to calculus."

15 Points Per Correct Answer - No time limit  



1. What is the exact value of pi?
    none of these
    22/7
    3.14
    both of the above


2. The Pythagorean theorem is best proved by using:
    simple calculations involving the areas of squares and triangles
    eigenvectors
    complex calculus equations
    trigonometric substitution


3. What is the derivative of (pi*e)a with respect to x?
    a(pi*e)a-1
    (pi*e)x
    ln(a)*(pi*e)a
    zero


4. What is a recursive series?
    a polynomial expansion
    a series whose first term is higher than its last
    a series that derives its next term from the one preceding it
    a series involving imaginary numbers


5. In statistics, if you were faced with an exponential regression equation that was spitting out numbers too large to work with, you might do which of the following?
    run a t-test
    do a hypothesis test
    try a linear regression
    linearize the data


6. What is the relationship between the volume of a tetrahedron and a parallelepiped (3-D form of a parallelogram) that shares the same three defining edges/vectors?
    The tetrahedron has 1/2 the volume
    The tetrahedron has 1/6 the volume
    The tetrahedron has 1/4 the volume
    The tetrahedron has 1/3 the volume


7. Which is NOT a way to find area under a curve?
    Simpson's Rule
    Integration
    Newton's Method
    Riemann Sums


8. If a$b means ab-ba, a@b means a+b+ab, and a#b means a2-b2, what is 8#(3@(3$2))?
    2232-2223 (a very large negative number)
    0
    111
    15


9. Which is NOT a fundamental trigonometric identity? (An identity is an equation that is satisfied for all defined values of x.)
    sin2x+cos2x=1
    tan2x+1=sec2x
    1+cot2x=csc2x
    sin2x-cos2x=tan2x


10. Last one, so I'll go multivariable. What method could you use when trying to optimize a function subject to one or more constraints?
    Green's Theorem
    Stokes Theorem
    The Method of Lagrange Multipliers
    Gauss-Jordan Elimination
