I think everyone’s mathematical journey would have been so much easier if they showed you the sine, cosine, and tangent unit circle (R=1) animation in precalc
Below is sine and cosine graph in relation to circle (R undefined)
Below is tangent graph in relation to circle (R=1)
below is all six trigonometric functions on unit circle (R=1)
i have to be honest this makes it worse
it’s very nice to look at but i think i actually understand less
