11 pages of my handwritten Precalc extras from class. All my own work, not textbook copies. What's inside: • 1x Fully filled Unit Circle (all degrees 0-360, radians 0-2pi, coordinates) + quadrant positive/negative rules for all 6 trig functions • Harmonics / Sinusoidal examples: how to find Amplitude, Max/Min, Vertical Shift, Period (ex: y=4cos(t/2)+5) with graphs • Cotangent examples: cot(pi/4), pi/2, 3pi/4, solving cot(x)=sqrt(3) with graphs y=cot(x) • + 8 more pages of extra examples, drawings, and steps. I got a 83.6 in the class, these are the extra practice pages that helped me remember.
