These videos are 40 times more valuable than lecture, the text book, and so much cheeper and efficient than a private tutor.

Just wanted to drop a note and thank you for this amazing service! And thank you for working hard on this, it is greatly appreciated :D

The videos were extremely helpful. You can play them over and over and pause them to review. The narrator explained the steps beautifully and provided details on performing the algebraic manipulations. Different colored pens made it easy to differentiate steps. My Physics teacher often moved through the material very fast in class. The videos allowed me to review areas I found difficult as many times as I needed. Giancoli Answers was a wonderful learning tool for understanding Physics.

This is a wonderful service. He goes over all of the problems of each chapter and gives both the answer in a quick text form (good if you are on your cell in the library etc) AND has a video which explains the entire problem if you want a detailed explanation. It's like having a tutor, which is a huge help! The cost is reasonable especially for the instruction you get-and WAY cheaper than the ripoff answer guides that the textbook business wants to force you to buy. Give this a month try and i promise you will want to keep using it. Huge help.

Features

• 1,930 video solutions for all regular problems in Giancoli's 7th Edition and 1,681 solutions for most regular problems in the 6th Edition.
• Final answer provided in text form for quick reference above each video, and formatted nicely as an equation, like $E=mc^2$. This is useful if you are in the library or have a slow internet connection.

• Pen colors make the solutions clear. Red is used to illustrate algebra steps, and to substitute numeric values in the final step of a solution. When a solution switches to a new train of thought a different pen color emphasizes the switch, so that solutions are very methodical and organized.
• Solutions are classroom tested, and created by an experienced physics teacher.
• Videos are delivered with a high performance content delivery network. No waiting for videos to load or buffer.
• Pause, rewind, repeat, and never miss what is being said.

Sample solution

Giancoli 7th Edition, Chapter 4, Problem 62

(1:36)

Giancoli 7th Edition, Chapter 1, Problem 37

Yes gheewala_jen4u, you got it, $\dfrac{L}{T^4} \times T^3 = \dfrac{L}{T}$. We multiply each term by whatever units are necessary to end up with $\dfrac{L}{T}$.

Giancoli 7th Edition, Chapter 1, Problem 37

can you help me explain this? does (L/T^4)T^3 give you L/T?

Giancoli 7th Edition, Chapter 1, Problem 10

Hi gheewala_jen4u, you're quite right, and thank you for spotting that. The final answer should be multiplied by 100, and since this is an error, for which only 1 significant figure is normally appropriate, we can round that to 10%.

Thanks again,
Mr. Dychko

Giancoli 7th Edition, Chapter 1, Problem 10

Should it not be 14.29% if you are multiplying by 100 to get percent?

Giancoli 6th Edition, Chapter 27, Problem 37

Can you put the solution to problem 35 on here please?
