Web27 feb. 2024 · Cosine is just the sine shifted by 1/4 of a period. if you are asking about the significance of sine and cosine, they are mathematical functions that represent a repeating waveform of a single frequency, and fourier series allow you to represent any arbitrary repeating function as a sum of sin and cos functions. Bob. WebThe law of sines always “works” when you have all acute angles. It’s only when the angle in question is an obtuse angle that we have a problem. (and, as @GMichaelGuy pointed out, it always works, it just makes us do a little more work.) Notice I used the arcsine. Turns out, the arcsine isn’t a function. Which means when you “undo ...
