MHB Sketch the sinusoidal graphs that satisfy the properties

AI Thread Summary
To sketch the sinusoidal graph with a period of 4, amplitude of 3, and an equation of the axis at y = 5, the maximum value will be 8 and the minimum value will be 2. The angular velocity $\omega$ can be calculated using the formula $\omega = \frac{2\pi}{T}$, resulting in $\omega = \frac{\pi}{2}$. The sinusoidal function can be expressed as $f(x) = 3\sin\left(\frac{\pi}{2}x\right) + 5$. This function will complete 2 cycles within the specified period of 4. The graph will oscillate between the maximum and minimum values around the axis at y = 5.

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?
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
