Answer 2

so like pi/4 +npi

Answer 3

sin x=cos x
sin x/cos x=1
tan x=1
tan x=tan 45

Answer 4

when i graph the equations they intersect at pi/4 and at 5pi/4

Answer 5

I'm confused about what you're saying

Answer 6

tan x= tan(n*180+45)
n=0;1;2;3........

Answer 7

these are my options

Answer 8

none of them seem satisfactory

Answer 9
