Homework

  • Week 7 (Due Monday 3/24) Section 7.5 #2, 3, 5, 9, 22; Section 7.6 #1, 2, 9, 10

    Writing: Find the surface area generated by rotating the ellipse $x + 4y^2 = 1$ around the $x$-axis. (Extra Credit) Do the same thing for the generic ellipse $\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$.

  • Week 6 (Due Monday 3/10) Section 7.4: #1, 2, 3, 5, 11, 29, 34; Section 8.8: #1, 2, 12, 13, 21, 25

    Writing: Can you use integration by parts to evaluate $\int x^{1000}e^x \,\mathrm{d}x$? If so, explain what the process would be and why you know your process would eventually give an answer. If not, explain why the process won’t ever give an answer. (Please don’t actually try to compute this integral!) Do the same for $\int e^x \ln x \,\mathrm{d}x$. (Again, please don’t try to actually compute it!) Extra Credit: Consider the following seemingly paradoxical argument and explain what’s going on:

    “Use integration by parts on the integral $\int \frac{\mathrm{d}x}{x}$, with $u = \frac 1x$ and $\mathrm d v = \mathrm d x$. We get that $\mathrm d u = -\frac{1}{x^2}$ and $v = x$. Plugging those into the integration by parts formula and simplifying we get $\int \frac{\mathrm{d}x}{x} = 1 + \int \frac{\mathrm{d}x}{x}$. Cancel out the integrals on the two sides and conclude $0 = 1$.”

  • Week 4 (Due Wednesday 2/26) Section 6.6: (only find the mass and center of mass) #1, 2, 3, 39, 40, 41, 42; Section 6.7: #1, 2, 3, 6, 14, 16, 23, 33.

    Writing: The exponential distribution with parameter $\lambda$ is the probability distribution with density function $\rho_\lambda(x) = \lambda e^{-\lambda x}$, where $x \ge 0$. Confirm this really is a probability density function and determine its mean. [Hint: what is the derivative of $-e^{-x} - xe^{-x}$?] (Extra Credit) The Cauchy distribution with parameter $\gamma$ is the probability distribution with density function $\rho_\gamma(x) = \frac{1}{\pi\gamma[1 + (\frac{x}{\gamma})^2]}$, where $x$ can be any value. Confirm that this really is a probability density function and determine its mean. Explain.

  • Week 3 (Due Monday 2/17) Section 6.3: #1, 2, 3, 5; Section 6.4 #1, 2, 4, 13, 14; Section 6.5 #1, 2, 9, 10, 16.

    Writing: Using integration, give an explanation to justify the formula $A = 4\pi r^2$ for the surface area of a sphere of radius $r$. (Extra Credit) Write a computer program which uses numerical integration (Riemann sums, trapezoidal rule, or Simpson’s rule) to approximately calculate arc lengths of curves $y = f(x)$.

  • Week 2 (Due Monday 2/10) Section 6.1: #1, 2, 5, 6; Section 6.2 #1, 2, 3, 6, 10, 12, 27, 28, 47, 49, 50

    Writing: Using integration, give an explanation to justify the formula $V = \frac{\pi}{3}r^2 h$ for the volume of a circular cone of radius $r$ at the base and height $h$. (Extra Credit) A regular tetrahedron is the solid with four faces, each an equally sized equilateral triangles. Determine a formula for the volume of a tetrahedron with side length $s$, and give an explanation to justify it.

  • Week 1 (Due Monday 2/3) Extra Problems Page 41: #9, 12, 14, 17; Extra Problems Page 103: #31, 32, 34; Extra Problems Page 234: #7, 9, 10, 29, 30.

    Writing: Write the statement of the fundamental theorem of calculus (both parts!) and give an informal explanation for why it is true. (Extra Credit) The Transfer Principle says that any equality or inequality about real functions true in the reals is also true in the hyperreals. We could formulate the same principle but going from the rational numbers to the real numbers: “Any equality or inequality about rational functions true in the rationals is also true in the reals.” Is this rational to real transfer principle true or false? Justify your answer
