Reflections and trigonometric graphs
y = −f(x) and y = f(−x), the graphs of sin x, cos x and tan x, exact values, and solving sin x = k and cos x = k.
You will be able to
- Reflect graphs and points: y = −f(x) and y = f(−x)
- Recall exact values of sin, cos and tan
- Solve sin x = k and cos x = k for 0° to 360° using the graphs
