This summer I am planning to post more Chemistry Worksheets and Wise Guys Videos in my blog. The following Worksheet named as Balancing Chemical Equations contains naming the type of Chemical Reaction as well, such as single replacement reaction, Syntheses reaction, Decomposition reaction, etc. If you have any questions, do not feel hesitate to ask me. Again, my email address is: email@example.com

In order to help your Calculus final review effectively, here I post a derivative worksheet (5 Practice questions) and Solutions. Solution(1) is using Quotient Rule to find the derivatives, and Solution(2) is using Logarithmic Differentiation to find the derivatives.
Solving a Math question by using different methods is one of the strategies of proving your Math skill. it helps you finding the internal relation between different operations, and comparing which method is the easiest.

Here are two Calculus worksheets named as Algebraic Substitution. Using this method the original function becomes much simple, and this enable us to integrate the composite functions effectively, in addition, from the second worksheet you will find the original functions are related to radicals, and after substitution radicals are eliminated, so we call this kind of Algebraic Substitution as Rationalizing Substitution. Hopefully, these two worksheet will help you to prep your final exam.

How to solve Three Sets Venn-Diagram Problems when the centre part number is not given?
Here is a problem you can try by using any method. In my solution I use algebraic method to solve it. I feel it is easier by using this method.

A student, taking 40s Applied Math, needs help for a Three Sets Venn Diagram problem. The question is:
A survey of students in a school cafeteria had these results:
- 50% of the students drink bottled water.
- 56% eat fruit.
- 43% follow a low-fat diet.
- 22% drink bottled water and follow a low-fat diet.
- 23% follow a low-fat diet and eat fruit.
- 27% drink bottled water and eat fruit.
- 15% drink bottled water and, follow low-fat diet, and eat fruit.
What percent of the students do not drink bottled water, do not follow a low-fat diet, and do not eat fruit?
For solving a Venn Diagram problem, there is no exact formula can be followed but using logical thinking and organizing the given information. You can solve the problem by writing the given information in U (Union) and ∩ (Intersection) set notation method, or filling the given information into a three circles Venn Diagram method. For detailed solution please read: Solve Three Sets Venn – Diagram Problems (1)

As the final is coming soon, I am going to post more worksheets with detailed solution in Physics and Math ( both Pre- Cal and Calculus). The subjects of the new post may not follow the exact order of the Chapter of your book but depending on students need. That is, first come, first service. It is my pleasure to help students who want to learn.

Hi all, Finding Force of Tension (2) & Solution is available now. This is an interested practice question which I got it from another instructor. It talks about three strings are connected at a knot with a block of cheese, a mouse and a piece of wall. The mouse is trying to pull the block of cheese down from the table but due to an enough static friction between the cheese and the table, so the mouse is just hanging on the string…, then you are supposed to find the maximum friction between the block of cheese and the table, the force of tension in strings, and the weight of the mouse. Would you try this question? Let me know if you have any difficulty. I’m willing to help you.
