Ch. 11-7, The Trigonometric Ratios ==> sine, cosine, and tangent. Memory aid: SOHCAHTOA. Finding the sin, cos, and tan of angles, finding the angles that have a value for their sin, cos, and tan, these are the "inverse" sin, cos, and tan functions written as sin-1, cos-1, and tan-1.
Table of Sin, Cos, and Tan from 0 to 90 Degrees - click here for copy.
This link has a simple online calculator used to use the find the sin, cos, and tan of an angle or, by putting in the value of the sin, cos, or tan you can find the angle by using the "INV" sin-1, cos-1, and tan-1 function. Read the short instructions before using this online calculator. It worked fine on my browser, your mileage may vary. There are too many online calculators to count, if you don't like this one find one you do like! Any spreadsheet (like Excel) will also do trig functions.

This also means never leave a fraction under a radical since the bottom is a radical. Adding and subtracting radical expressions ==> expressions with like radicals can be combined.

The meaning of a positive discriminant (2 real roots = parabola crosses x-axis twice), a zero discriminant (1 real root = parabola vertex is on the x-axis), and a negative discriminant (0 real roots = parabola never crosses x-axis).
Homework:
(1.) Read Ch. 10-2,
(2.) Page 535-536 #1, 2, 4-6.

Ch. 10-1, Graphing Quadratic Functions (Parabolas) ==>
y = f(x) = ax2 +bx+c where x = -b/2a is the axis of symmetry and the x-coordinate of the vertex and, if a is positive the parabola opens up and if it is negative the parabola opens down. Memory aid: positive a = "smiley face" parabola. Also, using symmetry to build a "smart" T-Table. Using f(-b/2a) to find the y coordinate of the vertex. Maximum and minimum values of the parabola.
Homework:
(1.) Read Ch. 10-1,
(2.) Page 528 #1 - 3, 6, 9, 18.

The geometry of a parabola. Definition of a parabola's directrix and focus. The geometric definition of a parabola as the set of points in a plane equidistant from a line (the directrix) and a point (the focus). Finding the equation of the "axis of symmetry" ==> the vertical line that cuts a parabola in half, its equation is x = -b/2a. Construction of a parabola using a directrix and focus and wax paper.
Homework:
(1.) Good luck at state Freddy and Phil!
(2.) Look up "parabola interactive" in Google and explore the parabola's properties. Here are some good parabola examples if you can't find any:

Return/review graded Homework 4/Quiz 4. Ch. 9-5 and 9-6, factoring a "difference of squares" ==> a2 - b2 = (a-b)(a+b) and factoring "perfect square trinomials" ==> (a+b)2 = a2+2ab+b2 and (a-b)2 = a2-2ab+b2. Solving equations by taking the square root of both sides ==> make sure your solution has a plus or minus in front so that you find BOTH solutions. How to find the square root of a fraction.

A factoring shortcut: when factoring quadratics if a = 1 you don't need to factor by grouping, you can write the factors using the two "magic numbers." Definition of the discriminant d = b2 - 4ac and using the discriminant to determine if the quadratic can be factored or not, unless d is a perfect square the quadratic can not be factored - in other words, the magic numbers don't exist.
Homework:
(1.) Page 499 #14 to 25 + find the discriminant for each problem and interpret it.

Return/review graded Homework 3 and Quiz 3.
Solving quadratic equations in standard form by factoring using the "magic number" method. That is, solving:
ax2 + bx+ c = 0 by finding two magic numbers whose:
sum is b and whose product is ac.
Use these numbers to split the middle x1 term into two terms then factor the resulting 4-term polynomial by grouping. Once factored, use the Zero Product Property to find the two solutions to the equation.

Continue Ch. 9-2, FBG ==> Factor By Grouping. This is our second factoring technique for factoring polynomials (pulling out the GCF and undoing the Distributive Property was the first). FBG is used (tried, because it may not work since not all polynomials can be factored) on polynomials with 4 or more terms.
