    What is [x]?

    The largest integer less than or equal to x.

    What is the volume of a square pyramid?

    The volume of a pyramid is equal to one-third the product of its base area and height.

    Integrability of |f(x)|

    If f(x) is integrable on an interval, then its absolute value, |f(x)|, is also integrable on that interval.

    Prove the principle of mathematical induction using the well-ordering principle.

    The principle of mathematical induction states that if a statement is true for the first case and if it is assumed true for any kth case, then it must be true for the (k+1)th case. To prove this from the well-ordering principle, consider the set of natural numbers where the statement is false. If this set is empty, then the statement is true for all natural numbers. If the set is not empty, then it has a least element, which contradicts the assumption that the statement is true for the first case.

    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.
