Question

Find the points of inflection; 2csc(3x/2) (0,2pi)..describe the concavity

Answer 1

points of infliction come from the second derivative, do you have the second derivative

Answer 2

9/4(cos(3x)+3)csc^3(3x/2)

Answer 3

okay, now you must determine where or at what values this derivative is zero

Answer 4

omg i only have 2 mins left!!!omg omg do u mind just giving me th points.....its a timed homework exam!:(

Answer 5

:'(

Answer 6

no inflection points

Answer 7

how would u desribe the concavity

Answer 8

concave up
(0,2pi/3)
(4pi/3,2pi)

Answer 9

concave down (2pi.3,4pi.3)

Answer 10

concave down (2pi/3,4pi/3)

Answer 11
