Hey guys,
Thanks for checking out my page! Just wanted to say a quick hello and introduce myself. Whether you're looking to boost up your grade, gain fluency, or learn Spanish for professional purposes, I'm here to help.
Let's...

Hi everyone,
Here is a video prepared for my German student for practicing English pronunciation.
Thanks.

Hi, I'm Vicki, bilingual tutor...
Here to help you learn English (ESL), or Chinese! :)

This timer will help you practice TOEFL Speaking Questions 1 and 2. This video provides preparation and response timing.

I cover both the case of a monomial dividing into a polynomial, and the case the monomial is not a factor of the polynomial. Give it a view and tell me how you like it.

Learn Spanish and sign Language with me.... feel free to contact me.

Hi everyone :D I made this lesson for those interested in learning how to play the song "Hotel California" by the legendary band The Eagles. This is a song I am currently studying with a student and I will have the tabs for it soon...

Hello everyone. I made this performance just for you to see how the song (by the great band Death Cab For Cutie) really goes and to make sense of the guitar tabs I am giving you. I've worked on this song with a few of my students back...

Hello my dear friends. I made this brief lesson to get you to see how the song should go and how it all comes together. If it doesn't make sense, please don't hesitate to ask. Thanks and enjoy :D

This animation represents level surfaces of the function f(x,y,z) = x^2 +y^2 -z^2. The graph of this function is a 3-dimensional solid in a 4-dimensional space - a hypersurface!

Although one often thinks of a gentleman's hat, a cylinder is any surface generated by dragging a curve in the 3 dimensional x, y ,z coordinate frame along the x, the y, or the z-axis.
In this particular example, the cylinder is generated...

The paraboloid z = x^2 + y^2 has a much simpler formula in polar coordinates. This formula is z = (r cos t)^2+(r sin t)^2 = r^2.

Basic tutorial on how to represent real world situations (i.e. Pizza!) into fractions and percents.

This is a sample beginning phonics online lesson.

The surface z = x^2 -y^2 is generated by sliding the curve z = -y^2 from the y-z plane along the curve z = x^2 in the x-z plane.

The surface z = (x^2 - y^2)/(x^2 + y^2) has the simple equation z (r, t) = Cos (2 t) in cylindrical coordinates. The surface is therefore obtained by wrapping the graph of the curve z = Cos (2 t) on a circular cylinder and then expanding this...

In this video, I walk through how to use dimensional analysis to solve the question: How many seconds are in one year?
Information that I used
1 year = 365 days
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
The...

This video describes the history of Microbiology from its inicial use of lenses by lenscrafters and cloth merchants interested in the microbial world, to the developments of microscopes by Galileo Galilei and other naturalists to the final debate...
