I'm only confuse of the term unlimited I know there is the method of just subtracting the squared Cosine of the other angles from one to get the third though I'm unsure about the term unlimited since even though I know that's a method I Dont know if its the only method

cosine The question was asking whether the statement ' cosine means the y component of a vector over its magnitude'. Is this true or false?

they sum to 1
