Find an angle Θ that makes each statement true Find cos(s+t) and cos(s-t) Please see the attached file for the fully formatted problems

    Proving Identities

    We have been working on proving identities and it's a subject I just can't get my brain around. A few of the problems we've been given have made me stumble. cotx/1+tan(-x) + tanx/1+cot(-x) = cotx + tanx +1 I figure on this one, with using identities, I can get: cotx/1-tanx + tanx/1-cotx = cotx + tanx +1 But I can't g
