Question

6. Find the amplitude of each function below- if no amplitude exists, write NA. a) y sinx b) y = - 3 cos (x) c) y = 2 tan (x) 7. Which of these functions is considered to be an odd function. a) y = cos(x) b) y =tan(x) c) y = sec (x) 8. Give me one value x with 0<x< 2 so that the following function is undefined at that angle. a) y = tan x b) y cotx y = sec x 9. Sketch the graph of (all x and y intercepts should be included/ labeled in terms of coordinates ) If the curve has an asymptotes, it (they) should be drawn and labeled (such as x = 3 ...) more than one period should be included portions of graph to the left of y-axis should always be included) a) y = 2cos x b) y = cotx
answer all please

Answer 1

And y = 72 sinne amplitulle = 2 / (1-1) so amplitude = 7% (b) y=-3 (053 coste (111 I ampletude = 3 (c) y= = 2 fanleg 4anx El-coas so amplitude os OX NA Q:7 y = (05 (25) y (-x) = (051.6%D) – (05 (-x) = cosfee) { cos (2)=(052 even flm so had a odd flm

y = tanke) y = Sant-se) = odd funtion - Wah x y 10) - Secky y = Ycos (2) yl-x) = cos(-x) = cose Odd funtion so only (b) y=tana = tank is odd fin not a a) y = tan se sinx cosa Where sinx. Eltil) so where losx=0 fln become undefined so losze o 2= 2 1 3 -= 7 237 flm is undefined sa x

(6) y= = cota y = cosa sina where sinu=o fin undefined anx: 2T - ot, so X= is the point C) y= seca y = cosa where cosa=0 fln undefined Cusse=0 K = 플 37 so fin is undefined at ate at este 37
