Hey,
I am really struggling to find the alternate solutions of sin and cos . Like I get the graph and stuff but somties I don't get when we do 180 minus. Is there like a fixed way to find them?! love

You do 180 - when you are dealing with sine.
You do +- when you are dealing with cosine.

Have you tried CAST diagrams
nope how would that work in terms of additional solutions.

sorry what do you mean by plus or minus

cos(x) = cos(-x)
E.g. cos(60) = 1/2 , so cos(-60)= 1/2 (which is the same as cos(300) = 1/2)
