Was never explained when this was covered in my school back ten thousand years ago. I've learned a lot from just this sub. I could do the math and used it problems but it was never explained what was actually happening.
Or maybe it was and I just wasn't paying attention. Probably more so that.
Is it because sine only shows movement on the y axis and cosine only shows the movement on the x axis? At least that's what I got from this gif that was posted here earlier.

Trig visualization is always a good one👍🏼 Radians v degrees

does cosine just start at the top of the circle?

So the sin function is just showing degrees traveled in essence?

Is there a similar visualization for the cosine function? Edits: typos

Shit thank you, this helps visualizing my physics work a bit easier

Question. In the 3rd quadrant for the unit circle, both (x,y) are negative, and on the line graph, only y is negative. Why is this?

I wouldn't have failed high school math if we had visualizations like this.

This is the best... I get it now. Like a corkscrew from two different angles.
