I have been enjoying learning math throughout my life. I like solving puzzles, and challenge to solve difficult problems. However, this gift does not extend to chemistry. I used to be struggling in chemistry, but changing the study habit makes me confident that I could overcome difficult obstacles in life. I have earned my PhD in organic chemistry, and since this is a tough subject to master especially for pre-med students, I like teaching my study techniques and preparing for exams in order that my students to succeed in this class. So, if you have any difficulty in chemistry, especially organic, don't hesitate to hire me.

Besides chemistry, I am also very knowledgeable in mathematics up to differential equations. So, elementary math, prealgebra, algebra,1 and 2, geometry, trigonometry, precalculus, and calculus 1-3 are the math classes I could tutor. I really enjoy math ever since grade school.

Approved subjects are in **bold**.

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

I received all A's in all my calculus classes. I really enjoy tutoring this subjects because it opens up the whole new dimension in learning math.

I have been tutoring general chemistry privately and with tutoring centers for more than 10 years. Also, I was a teaching assistant while in graduate school, teaching a laboratory of 20 students making sure that they were safe and could relate to the class material.

I got an A in the differential equation class. I also got an A in Physical Chemistry class in which utilized a lot of differential equations as part of the problems. I enjoy teaching differential equation because it is nice extension to calculus.

I have been tutoring organic chemistry for more than 10 years. This is my strongest subject, since I got a graduate degree in organic chemistry. I was also working as a supplementary instructor leading discussion sessions outside class.

Integral Problem (answer)

They are essentially the same function. I think both answers should be zero. Only the first integral question utilize more complex approximation, but the answer is not that much different. −1.110223024625157×10−16 = -0.0000000000000001≈0

What am I doing wrong (answer)

The first step is wrong. You could not distribute like that. You should live it like that. Just do the following: 2x+5=53 2x= 125-5 x=60

Find the asymptotes? (answer)

x=1/t --> t=1/x replacing it to y=t/(t+1) = (1/x)/(1/x+1) = 1/1+x The equation has horizontal asymptote at y=0 and vertical asymptote at x=-1 ...(C)
