Today we had a lesson on probability. We got examples of sample spaces, the first one was with a four sided die and a coin. Also we expanded and learned there are two event types, Simple and compound. To solve these types of questions there are formulas: the addition law "Or:, and the Multiplication law "And".

Today we had a lesson on the standard form of cAWnics. We learned were given both hyperbola formulas, and we were given examples, i got a little lost and im confused.

Our lesson today was on graphing analysis of conics. We learned the equations of an ellipse and a hyperbola, there are two for each. The equations change slightly, and there are two for each because each conic can be flipped the opposite way over the axis. I graphed and followed along, and found that this unit is quite easy, i also understand how to analyze the graphs, good job jenna:)

Today we had a new lesson on Conics (Prononuced Cawnics). There are four types of Conics, Circle, Hyperbola, Ellipse, and Parabola. We learned all of the differences in each, and how to determine which graph willl come out of the conic equation. We played a a bit on graphmatica and on a site Mr Max found, actually leraned a bit today, and am quite proud of myself.

Yesterday, we learned a new unit called the Binomial Theorem. The first five equations he gave us all followed a pattern: *the sum of the exponents were equal to the power of the binomial
*Exponents of the first term in each begins with the same value as the power, and decreases by one in each term
*number of terms is one more than the power
*coefficients are combinations of the power number
Each one of the binomial expansions got bigger as their exponents got bigger, showing us pattern that relates closely to Pascal's triangle. After looking at the diagram i wasn't quite sure what it had to do with math, so i googled it, a useful site i found was this, http://mathforum.org/dr.math/faq/faq.pascal.triangle.html
