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. It 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.

This is my attempt to introduce the mystery and wonder of irrational numbers and their link to our naive notion of cause and effect. The followers of Pythagoras believed: "All is number"! Have you ever truly wondered what they meant?

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!

Have you been to Lincoln Center? There is a curious structure that looks like a twisted roof. In the summer, this twisted roof is covered with grass. Well, it seems to me that the roof is just a rectangular cutout of the graph of the multiplication...

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...
