Question

Sketch the graph of the following function:

\[\psi\left( x \right) = 4 \sin 3\left( x - \frac{\pi}{4} \right), 0 \leq x \leq 2\pi\]

 

Answer 1

\[\psi\left( x \right) = 4 \sin 3\left( x - \frac{\pi}{4} \right), 0 \leq x \leq 2\pi\]

x	\[\frac{\pi}{4}\]	\[\frac{7\pi}{12}\]
\[\psi\left( x \right) = 4 \sin 3\left( x - \frac{\pi}{4} \right)\]	0	0
