Post one question and learn from the answer.

Then if you need to post another afterwards.

the parent sin funtion is

\(y=sin \theta\)

this has a amplitude of 1, a period of 2pi (radians) , the wave centre is the line y=0 (the theta axis) and no phase shift.

\(y=sin (n\theta) \)

This has a period of 2pi/n nothing else has changed

\(y=a\cdot sin \theta\)

This has an amplitude of a Everything else is the same as the parent function.

\(y=sin \theta+L\)

Lifts the parent funtion by L units.

Now what would be a good starting point do you think for this graph. It may need tweaking afterwards?

Now graph your function with desmos. Use x instead of theta, I do not think theta will work.

Ive started you off with the parent funtions. You add what you think is write underneath and see if it works.

If you interact with me I will be very impressed.

**Please no one answer over the top of me. I am attempting to help our guest learn.**

Am I doing this right? Also, I appreciate you.

**Yes that looks really good to me. Nice work! **

**And thanks for your gratitude, I appreciate it **

Did they want you to graph it like this or did they want you to do it with points? Do you know?

I modified your graph just a little bit. I used the spanner tool in the top right corner to sset the units to 1,2,3 etc instead of pi

And on the second graph y=1 I made it so it could not be moved by saying it had to be from 1 to 1.

If you look at my graph you will see what I mean.

Desmos is a wonderful grahing tool. It will be worth your while to learn to use it very well.

I just need a point at the midline and a point at the maximum or minimum closest to the first point. Thanks again.

I'll try and show you how to graph it by hand. I will be back in a little while :)
