Sketch the sinusoidal graphs that satisfy the properties

Click For Summary
SUMMARY

The discussion focuses on sketching sinusoidal graphs with specific properties: a period of 4, an amplitude of 3, an equation of the axis at y = 5, and 2 cycles. To determine the angular velocity $\omega$, the relationship between period and angular velocity is established using the formula $T = \frac{2\pi}{\omega}$. By substituting the period T with 4, the value of $\omega$ can be calculated as $\omega = \frac{2\pi}{4} = \frac{\pi}{2}$. This establishes the foundation for graphing the sinusoidal function.

12a) Sketch the sinusoidal graphs that satisfy the properties below:
Period: 4
Amplitude: 3
Equation of the Axis: y = 5
Number of Cycles: 2

So, I know how to graph sinusoidal functions, but I can't figure out the max and min that would satisfy both the equation of the axis and the amplitude listed.

Let's start with the angular velocity $\omega$. For a sinusoid of the form:

$$f(x)=\sin(\omega x)$$

The period is:

$$T=\frac{2\pi}{\omega}$$

This comes from:

$$f(x)=\sin(\omega x)=\sin(\omega x+2\pi)=\sin\left(\omega\left(x+\frac{2\pi}{\omega}\right)\right)=f\left(x+\frac{2\pi}{\omega}\right)=f(x+T)$$

So, letting $T=4$, what must $\omega$ be?
