Hexagon Construction
Complex Numbers
An "imaginary number" is a multiple of a quantity called "[i]i[/i]" which is defined by the property that [i]i[/i] squared equals -1. This is puzzling to most people, because it is hard to imagine any number having a negative square. The result: it is tempting to believe that [i]i[/i] doesn't really exist, but is just a convenient mathematical fiction. [br][br]the discriminant helps tell you the number of real solutions to a quadratic equation. The expression used to find the discriminant is the expression located under the radical in the quadratic formula! In this tutorial, get introduced to the discriminant of a quadratic equation!

Problem
finding the probability of selecting a black card or a 6 from a deck of 52 cards.[br][br]1. We need to find out P(B or 6)[br][br]2. Probability of selecting a black card = 26/52[br][br]3. Probability of selecting a 6 = 4/52[br][br]4. Probability of selecting both a black card and a 6 = 2/52[br][br]5. P(B or 6) = P(B) + P(6) – P(B and 6)[br][br]6. = 26/52 + 4/52 – 2/52[br][br]7. = 28/52[br][br]8. = 7/13[br][br]
summary
The experience I will remember the most from this class is andrew always saying funny things. The concept I understand the best is most likely finding area of a shape. Doing my work is the struggle I never want to do homework. The open box stuff was cool but i'm not very curious about math.
