Trigonometric functions and graphs

By the end you’ll be able to

• Use exact values of $\sin\theta$, $\cos\theta$ and $\tan\theta$ for standard angles.
• Sketch and interpret the graphs of $y=\sin x$, $y=\cos x$ and $y=\tan x$, including amplitude, period and asymptotes where appropriate.
• Use the unit-circle definition and symmetries of trigonometric functions.
• Apply graph transformations to trigonometric functions.
