Graphing Periodic Functions – Sine, Cosine, Amplitude and Period
We looked at periodic functions. Started most problems by finding the amplitude and the period. The amplitude is basically the absolute value of the coefficient multiplying the function. If there is …

Graphing Hyperbolas, Directrix, Focus
We worked on some upcoming material in the class with periodic functions. Drew an angle on the unit circle and found the tangent of that angle. You draw the angle and a right triangle then find the …

Tutoring Physics, Light, Indices of Refraction
We went over some problems with lenses, converging and diverging. Then spent some time on problems with different indices of refraction. I would usually think of air to water and the behavior if you …

Preparing for an Algebra Test
We went through the review packet for the test. One thing to watch for was to only combine like terms, so either numbers or variables with the same exponent. We saw the difference of perfect cubes …
Matrix Addition, Subtraction, Multiplication – Tutoring Math
We worked on matrices. Starting with matrix addition and subtraction, which were not a problem. Then got into multiplication by numbers as well as addition and subtraction. Sometimes factoring was …
