The above function is in the form .

, ,

Here .

The relation between period P and B is .

So, in the given equation Amplitude , stretch .

The period of the function is

Now the phase shift of the function is

Since the period of the sinusoidal function is .

The solutions of the given function are

So, is one cycle of the function.

Now find key points using interval difference .

\              x \		\         \	\          \	\                  \	\        \
\                y \	\           -3 \	\          0  \	\         3 \	\          0   \	\         -3   \

Graph of one period of the function is

Similarly find the amplitude, period and phase shift of this function.

Amplitude ,, .

Period

Phase shift .

The solutions of the function are

So, is one cycle of the function.

Now find key points using interval difference .

\              x \		\         \	\          \	\                  \	\        \
\                y \	\           -4 \	\          0  \	\         4 \	\          0   \	\         -4 \
