    Study Notes

    Practice Exam 1

    • Problem 1: Calculate the definite integral $\int_{}^{} (2x - 198)^{2} [\sqrt{x} - 99] dx$. The function includes the greatest integer function.

    • Problem 2: Find the volume of the square pyramid using Cavalieri's theorem. The pyramid has a base area of $r^2$ and height $h$.

    • Problem 3: Prove that the absolute value $|f|$ of an integrable function $f$ on the interval [0,1] is also integrable.

    • Problem 4: Show that the well-ordering principle implies the principle of mathematical induction. This involves a set $S$ of natural numbers, and a subset $T$.

    • Problem 5: If the limit of a function $f(x)$ as $x$ approaches $p$ from the left and right both equal $A$, prove that the limit as $x$ approaches $p$ is also $A$.

    Practice Exam 2

    • Problem 1: Evaluate the limit $\lim_{h\to0} \frac{\int_{0}^{1+h} e^{t^2} dt - \int_{0}^{1} e^{t^2} dt}{h(3+h^2)}$, using a theorem.

    • Problem 2: Find the derivative of the inverse function $(f^{-1})'(0)$, for a specific function $f(x)$ involving a definite integral.

    • Problem 3: Find the value of $f(2)$ given a definite integral equation. The function $f(x)$ is continuous.

    • Problem 4: Provide an example of a function $f(x)$ on the interval [-1,1] that is continuous and differentiable but whose derivative $f'(x)$ is not continuous at certain points.

    • Problem 5: Demonstrate that if $f(x)$ is continuous on [0,1] and $f(0)=f(1)$, then there exists a point $x\in[0,1]$ such that $f(x)=f(x+1/n)$ for any positive integer $n$.

    Practice Exam 3

    • Problem 1: Evaluate the integral $\int_{}^{} \frac{t + t^2}{\sqrt{1 + t^2}} dt$

    • Problem 2: Calculate the integral $\int_{}^{} x^2 \sqrt{x^2 - 9} dx$

    • Problem 3: Given $\lim_{x→a^+} g(x) = B$ (a finite, non-zero value) and $\lim_{x→a^+} h(x) = 0$, with $h(x) \neq 0$ near $a$, prove that $\lim_{x→a^+} \frac{g(x)}{h(x)}$ is infinity.

    • Problem 4: If $f(x)$ is a positive continuous function on [0,$\infty$) with $\lim_{x→∞} f(x) = 0$, prove that there exists a maximum value $M$ for $f(x)$ on the interval [0, $\infty$).

    • Problem 5: Demonstrate that a convergent sequence is a Cauchy sequence. A function $f$ is a contraction if there exists 0 < a < 1 such that $|f(x) - f(y)| ≤ a|x-y|$. Show that if $f$ is a contraction in the composition of $f$ on itself $n$ times, the sequence formed is Cauchy.
