Best ResponseYou've already chosen the best response.2To start, look at where x = 0. since y equals zero at that point as well, you can eliminate any possible choices which don't equal zero at x = 0. x = 0: y = sin((0)  pi/2) = sin(pi/2) = 1, not an answer y = cos(0  pi/2) = 0, possibility y = cos(0 + pi) = 1, not an answer y = sin(0) = 0, possibility y = sin(0 + pi) = 0, possibility y = cos(0) = 1, not an answer

Best ResponseYou've already chosen the best response.2you can then take another point, lets say x = pi/2 to eliminate any other answers 2. y = cos(pi/2  pi/2) = 1, possibility 4. y = sin(pi/2) = 1, possibility 5. y = sin(pi/2 + pi) = sqrt(3)/2, not an answer your answers are 2 and 4
