Yes, now that I've learned how to click the "pi" button on Microsoft Calc, I'm home free.

Looks like there's something weird going on with frequency and phase shift: Take 3.1415 as phase shift and then look at the graphs for the frequencies 1 and 2..
That 2.06 value I got with a frequency of 3: Look at phase shifts 0, 0.5, 1, 1.5, 2.06 ..

It looks fine for me: 2.06 radians as a phase shift with a frequency of 3 looks about right given that
3 * (2.06 / 2) = 3.09 ~= π

The effect of the phase shift should be independent of the frequency. A phase shift of π will always "flip" a sine graph horizontally. Now enter a frequency of 2 and look at the graphs for a phase shift of 0 and then 3.141

See what you mean, but I see what they are doing as well.

Don't think so:
f=2, p=0 -> draw yellow, add, add -> double amplitude
f=2, p=0 -> draw yellow, add; f=2, p=3.141 -> add -> double amplitude, should be flat.

Wikipedia: In general, mathematically important relationships between the sine and cosine functions and the exponential function (see, for example, Euler's formula) are substantially simplified when angles are expressed in radians, rather than in degrees, grads or other units. Therefore, in most branches of mathematics beyond practical geometry, angles are generally assumed to be expressed in radians.
And that's the case in .NET or JavaScript and Java and PHP too...All except radians and not degrees...

360 degrees is just for the stupid humans since we like whole numbers. Non-rational numbers aren't so nice for us.
Pi is a number to describe the relations in a circle, and it is basically how Sinus and Cosinus are defined.

Are you sure about that? The ratio of sides of a triangle is totally independent of the units used to measure the angle.

Well, its all connected:
Sin(2*pi*n) = 0
Without pi the Taylor series is sin and cosine is pretty much useless in Fourier Transform for instance.

I think that 2π is very nice...

Wouldn't that be iπ?

Your find is perfect for adding two waves. Thank you.
I am now on my own little quest to find some freeware/cheapware that will let me do the same thing with a bunch of functions, and then let me choose which graphs to add (e.g., add graph "A" to graph "B", and graph "C", and draw the result as the target graph, whatever). A wide across-the-screen strip would be cool.
Graphing was always the sore point for me in math courses. Today's kids don't know how good they have it with mathematical graphing.
Thirty minutes with DESMOS[^] and I made THIS GRAPH[^] which shows all the inputs, which is good. I also want to show my reader the output (i.e., the five waves added together as a single curve)
I found THIS PAGE[^] which could keep me busy for months just evaluating the 118 possible suitors.
Opinions / advice on these or others will be welcome.

IMHO, having the words - 'superpose', 'superposition' - may yield better results.

If you have problems finding this on google, you might just as well create a program that does it

Hold it, Microsoft Excel will do that, I think. Yes ? No ?
Will LibreOffice Impress also do the same thing ?
I seem to remember this from 3 or 4 years ago. We did this with some procedure.

No, please sir, not Excel. Its sooo crude that any person can use it
And dont get me started on the macros, one for every operation

I want to share my PC's internet connection with my phone and tablet. I googled it how do it and found this neat guide here. But when I enter this command in command prompt, netsh wlan set hostednetwork mode=allow ssid=enternetworkname key=enterpassword , it shows and error saying cmd.exe is not working. Any solution to this?

Possibly, but the Lounge is not the place for such questions.

Hi All,
I have had some Win 10 problems and posted relief that they appeared to be cured, Griff responded Okay. I can still see the messages in my profile, but can't see them on the page have they been deleted as spam?  , but yeehah still working.
