cot x can be rewritten as cos x / sin x so, sin x + cos x. cosx / sin x sin x + (cos x)^2 / sin x Then if you multiply by sin x... sin x. sin x + sinx. (cos x)^2 / sin x which becomes (sin x)^2 + (cos x)^2 I'll leave the honors to you.
Old Man River. NOTE Old Man River was a standard part of Robeson's repertoire and appears on many of his albums. It also became William Warfield's signature song. Show Boat's 1927 premiere announced the advent of a new kind of musical. For the first time, characters developed and matured.
Several musicians reflected the 1927 flood in their music: 1  When the Levee Breaks, by Memphis Minnie and Kansas Joe McCoy (famously covered by Led Zeppelin in 1971) 2  High Water Everywhere, by Charley Patton (referred to in High Water (For Charley Patton) by Bob Dylan in 2001) 3  Tupelo Blues by John Lee Hooker. 4  Louisiana 1927 by Randy Newman.
