Very well presented StarStrike. I am impressed !!!

What number? Can I use a calculator?

Thanks guest, your method obviously works

I like my method because it is tidier. I mean I don't have everything over my dsektop.

But I guess if you wanted you could dedicate a file to these types of saves and that way would make your method quite tidy.

Your method is certainly simpler in that no downlad program is needed.

Here is one of cupcakes's images

How would other people go about posting it as a pic instead of as a link.

I think....

To do that the file image would have to be uploaded somewhere already and only certain file formats would be accepted.

Is this correct?

I just tried to put in one of cupcake's pics your way CalculatorUser.

I thought it worked but the pic disappears when I go to 'show preview.'

The wavelength here is \(\pi \) and that is the only transformation from the parent function of y=cos x

If y= cos nx then the wavelength will be \(\frac{2\pi}{n}\)

so

\(\frac{2\pi}{n}=\pi\\ \frac{2}{n}=1\\ n=2\)

So it must be \(y=cos(2x)\)

Check by using Desmos graphing calculator.

Desmos is another tool that is very easy to use and very helpful to you.

I've just drawn your pic. I am not sure about some of it.

Plus I do not know what angles you want either.

Here is a thermometer.the temperature displayed on it is 1 degrees.

But say it is on 3 degrees and it goes down 5 degrees, what would it be then?

That is cute! I will try and remember that one :)
