I'm doing polynomials right now, but i'm curious. let's say we have ycubed + xsquared + ysquared + xcubed, does the x come first or does the y? like alphabetical or leave it how it is?

Any time you have multiple letter it is always in alphabetical order so it would be xy

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
