This resource provides a comprehensive review of essential trigonometric concepts for AP Calculus AB, including simplified radical forms, even/odd properties, and identities. Understand the relationships of trigonometric functions across quadrants I, II, III, and IV. Learn to analyze and graph sine and cosine waves with respect to amplitude, period, phase shift, and vertical shift. Gain skills in creating graphs by first plotting sine or cosine and then inverting points. Ideal for reinforcing foundational knowledge necessary for calculus.

AP Calculus AB Day 1 Trig (Appendix Section 3) Perkins
Give in simplified radical form. QII QIII QIV QIII
Even / Odd Properties Identities you should know: Compare the values of the trig function in QI and QIV.
Trig Graphs Amplitude Period Phase shift Vertical shift Height of each ‘wave’. Length of one ‘wave’. Re-center the graph at x = C. Re-center the graph at y = D.
Create these graphs by making the sine or cosine graphs first and then taking the reciprocal of each y-value. Amplitude Period Phase shift Vertical shift Only applies to sine and cosine. All are the same as sine and cosine
Amplitude Doesn’t really apply (not a wave) Gives a point the graph passes through Period Repeats twice as fast as sin, cos, sec, csc Phase shift, Vertical shift Same as sin, cos, sec, csc
Graph one period, beginning at zero. Amplitude Period Phase shift Vertical shift Re-center graph at
