Python Matplotlib Matplotlib — Visualization with Python [^] can do it for free.
By the way, am curious to know the name of the math book you're reading.
I have a small program (in JavaScript) to test our knowledge of Sines/Sinusoids - SineDrill [^]
modified yesterday.

It's free and way, way more feature rich than Excel or Calc. It has a steep learning curve with its built in command/scripting language but much easier than dealing with a library. Also, there are plenty of examples on their site to help you get started. It also has a ton of export formats, etc. I recently used it to analyze some data myself.
You can check out the demos to get an idea of what it can do and there are some YouTube tutorial vidoes to help get you started. Also, the video link covers plotting sine waves.

The built-in Calculator app in any recent version of Windows can plot these.
Then there is Microsoft Mathematics...

I'm now running MS Edge on my MacBook Pro M3 running Sonoma 14.4.1
I'm also running MS Edge on my desktop AMD R5 (12-core) running Ubuntu 22.04.4 LTS.
Also running it on my iPad (iOS) and I really like MS Edge so far.
Sharing history and links across devices is good (if you want to -- you don't have to).
I ran FireFox on all these devices but when I watched videos my Ubuntu desktop would lock sometimes -- became quite often.
Switched to Brave and had an odd issue.
Now I'm trying Edge and so far it's really nice.
I use DuckDuckGo as my default search engine. I try to switch it up: use different OS, different search engine, different "office" suite. Mix it up a bit.
Have you tried Edge? It's better than I expected.
This message posted from MacBookPro and MS Edge.

Mandatory at work. Not bad, but still annoying from time to time. Specially the new side-frame that pops up when you klick a link in an email or in teams.
I have noticed the performance loss in FF too... really sad. Luckily still in a decent level for me.

The side frame popups can be turned off via Settings -> Sidebar.

For me at least it gets reactivated few days after. Not sure if domain policy or minor "updates"

Would be domain policy. I've never seen this reactivate - not saying Microsoft won't do this, just that I've never seen it occur.

I like Edge.
Only that it suddenly starts using the webcam on my laptop, as indicated by a pop up message "Edge is using your webcam". Covered my webcam camera with an opaque sticker.

That is a very odd behavior. I wonder what is causing that??

Maybe it has AI thing to detect whenever i get a little edgy (its Edge, isn't it), so as to switch on the webcam
|

I've noticed that it's only certain websites where it wants to turn on the webcam, like my bank. I assume it is the websites, not Edge. But I don't know why my bank thinks they need my webcam on.

If a website can enable turning on/off my webcam, its kindof dangerous, isn't it? Sometime back, it was reported that Alexa records private conversations even when turned off - this will become similar to that. Privacy issues.

Settings ⇒ Cookies and site permissions ⇒ Camera
Do you have anything in the "Allow" list? If so, those sites will be able to use your camera without asking.
You can also turn off the "Ask before accessing" option, which will allegedly block any sites not already in the "allow" list from accessing, or asking to access, the camera.

Thanks for this info. Was not aware of this.
Just checked my cookies / camera settings. No site is allowed. Sometimes, this "Edge is using your Webcam" message comes even when Edge is not open. Hope this is not a virus on my laptop.

Use metal foil. Some stickers and tapes are opaque to visible light, but not to IR.

MS Edge is built off of Chromium since about 2020. MS rips out the Google telemetry and installs their own.
If it works for Chrome it should work for Edge.
I am glad they finally sealed IE in its crypt.

Sad to say, some of the rendering that works in Chrome fails in Edge.
And Egde's integration with Windows and its accounts can be a headache (erased profiles, etc).

That's interesting...and not great. I will keep an eye out for it.

That sounds like par for the user account course. MS has never been great at managing user accounts. I remember having a seriously difficult situation with an XBox account that was all intermingled with another account. Very confusing. Hopefully they'll work it out soon.

I've only seen this on Google's own pages.
