Question

y=4csc2(x-pi/2)

Answer 1

do you have a calculator at hand?

Answer 2

and what is the question?

Answer 3

just a sec

Answer 4

do you know to what value equals csc2(x-pi/2)

Answer 5

are u graphing this?

Answer 6

cscx=1/sinx---------->csc2x=1/sin2x

Answer 7

sin2x=2sinx*cosx

Answer 8

oh you wanted to solve for x

Answer 9

\[\csc2(x-\pi/2)=1/(\sin2(x-\pi/2)\]

Answer 10

you can look at it using introspection and see that it is phase shifted -pi/2, so pi/2 to the right, so at y=0; x=pi/2
