Biography

I am a recent graduate from the University of Washington with nearly ten years of tutoring experience. I've worked with students one on one and in a group setting, in person and remotely, synchronously and asynchonously, in all of math, computer science, physics, and engineering.

Outside of work I enjoy science fiction, making soap, and the rule of threes.

Calculus: Early Transcendentals

For the function $ f $ whose graph is given, state the value of each quantity, if it exists. If it does not, explain why.

(a) $ \displaystyle \lim_{x\to 1}f(x) $
(b) $ \displaystyle \lim_{x\to 3^-}f(x) $
(c) $ \displaystyle \lim_{x\to 3^+}f(x) $
(d) $ \displaystyle \lim_{x\to 3}f(x) $
(e) $ f(3) $

Use a graph to find a number $ \delta $ such that
if $ \left| x - 1 \right| < \delta $ then $ \displaystyle \biggl| \frac{2x}{x^2 + 4} - 0.4 \biggr| < 0.1 $

Calculus: Early Transcendentals

If $ H $ is the Heaviside function defined in Example 2.2.6, prove, using Definition 2, that
$ \displaystyle \lim_{t \to 0} H(t) $ does not exist. [$Hint:$ Use an indirect proof as follows. Suppose that the limit is $ L $. Take $ \varepsilon = \frac{1}{2} $ in the definition of a limit and try to arrive at a contradiction.]

Calculus: Early Transcendentals

Suppose that a function $ f $ is continuous on $ [0, 1] $ except at 0.25 and that $ f(0) = 1 $ and $ f(1) = 3 $. Let $ N = 2 $. Sketch two possible graphs of $ f $, one showing that $ f $ might not satisfy the conclusion of the Intermediate Value Theorem and one showing that $ f $ might still satisfy the conclusion of the Intermediate Value Theorem (even though it doesn't satisfy the hypothesis.)

Text: Linear Algebra

In 2018, there are an estimated 1.632 million people living in Manhattan and a total of about 8.4 million people living in New York City's five boroughs. Assume that each year about 4% of Manhattan's population moved out of Manhattan and into one of the other boroughs. Also assume that 3% of the population of New York City's four outer boroughs moved into Manhattan each year. For simplicity, also assume that there were no other migrations and that there is no population growth.

a. Calculate the distribution of the New York City population in terms of Manhattan and outside of Manhattan in 2019, 2020, 2021, 2022, 2023, and 2024. Assume the same migration trend for each year.

b. Predict the long-term New York City population distribution. If Manhattan's population capacity is three million, will the population of Manhattan reach capacity under this model? If so, when?

c. The above mathematical model is oversimplified. If you want to incorporate the growth rate or immigration from outside of New York City, describe how you could make the model more realistic. Please be specific.

Calculus 1 / AB

A flat circular plate has the shape of the region x^2 + y^2 ≤ 1. The plate, including the boundary where x^2 + y^2 = 1, is heated so that the temperature at the point (x,y) is T(x,y) = x^2 + 3y^2 - 2x. Find the temperatures at the hottest and coldest points on the plate.

The hottest temperature on the plate is ____ degrees.
The coldest temperature on the plate is ____ degrees.
