Trigonometry Β· April 23
Trig introduces 6 new functions. You need to be solid on what a function is, domain restrictions, and how to read function notation.
Section 6.3 is entirely about inverse trig functions (arcsin, arccos, arctan). You need to understand how inverses work β reflecting over y = x, domain/range swaps, and the horizontal line test.
Trig graphs (6.1, 6.2) use shifts, stretches, and reflections β the same transformations from linear/quadratic graphing. Amplitude = vertical stretch, phase shift = horizontal shift.
Many trig equations reduce to quadratics. For example, 2sinΒ²x β sinx β 1 = 0 is really 2uΒ² β u β 1 = 0 in disguise. You need factoring and the quadratic formula.
Radian measures like 5Ο/6 and trig values like β3/2 require confident fraction work β common denominators, simplifying, multiplying. This comes up in almost every trig problem.
Conics, Sequences & Series Β· May 14
Circles, ellipses, and hyperbolas all require converting equations like xΒ² + 6x + yΒ² β 4y = 12 into standard form. Completing the square is THE key technique.
The Binomial Theorem (11.6) expands expressions like (x + 2)β΅. You need comfort with polynomial multiplication, factoring, and exponent rules.
Geometric sequences follow the pattern aβ = aβ Β· rβΏβ»ΒΉ β the same exponential growth/decay from Chapter 4. You need exponent laws to simplify terms.
Some conic and sequence problems require solving systems (two equations, two unknowns). Make sure you can do substitution and elimination.
Series problems often involve fractions with variables. Simplifying partial sums and working with rational expressions is essential for summation notation.
