Trig Functions: Graphs of trig functions are the “unwrapping” of the circle in the coordinate plane. The sine function is all the y-coordinates all the way around the circle.
Sine Function: Sine Function This is an ODD function: A function with 180° symmetry about the origin. 1 -2π -3π/2 -π -π/2 π/2 π 3π/2 2π -1 Y-intercept? x-intercepts? Period? Max and Min? Domain? Range?
Cosine Function: Question: Does anyone notice any relationship between the graphs of the Sine and Cosine Functions? This is an EVEN function: A function with Reflection symmetry over the y-axis. 1 -2π -3π/2 -π -π/2 π/2 π 3π/2 2π -1 Max and Min? Domain? Range? Y-intercept? X-intercepts? Period?
Tangent Function: Question: Is this an Even or an Odd Function? Or Neither??? 1 -2π -3π/2 -π -π/2 π/2 π 3π/2 2π -1 Max and Min? Domain? Range? Y-intercept? X-intercepts? Period?
