all right , let 's see if we can find the limit of 1 over the square root of 2 sine of theta over cosine of 2 theta , as theta approaches negative pi over 4 . and like always , try to give it a shot before we go through it together . well , one take on it is well , let 's just , let 's just say that this is going to b... | so if i have 1 plus the square root of 2 , sine theta , over cosine 2 theta , as you can imagine , the things that might be useful here are our trig identities and in particular , cosine of 2 theta seems interesting . let me write some trig identities involving cosine of 2 theta . i 'll write it over here . | is it required for ap calculus ab to memorize all the trig identities ? |
