Question
Sketch the graph of (a) $y=\cos t$ in the interval $[0,2 \pi)$ and (b) $y=\tan t$ in the interval $\left(-\frac{\pi}{2}, \frac{3 \pi}{2}\right)$
Step 1
The cosine function, $y=\cos t$, has an amplitude of 1 (the peak deviation of the function from zero), and a period of $2\pi$ (the length of one complete cycle of the function). Show more…
