Write an equivalent expression for cos^4 theta that does not involve any powers of sin or cosine greater then 1.

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Which function is odd check all that apply a. y=sin x b. y=csc x c. y=cot x d. y=sec x

1. if events a and b are non-overlapping events, how do you find the probability that one or the other occurs? 2. what does it mean if p(a or b) equals 1?
