Question

another help!!! how do i find the x and y intercept from a graph i.e. y=cos(5x/6+pi/3)

Answer 1

**3cos

Answer 2

x - intercept means y=0
y - intercept means x=0

Answer 3

cos(5x/6+pi/3)=0
so solve for x

Answer 4

y=cos(pi/3) is the y intercept

Answer 5

y=1/2 is the y intercept

Answer 6

wait sorry u said 3Cos

Answer 7

yes

Answer 8

y=3cos(5x/6+pi/3)

Answer 9

yes

Answer 11

Y intercepts:
y=3cos(pi/3) = 1.5

Answer 12

* there's only one y intercept btw

Answer 13

Please click on Good Answer if I helped, I really want to get to the next level, thanks =)!

Answer 14

thanx!!!

Answer 15

np

Answer 16

its wrong.. cos(5x/6+pi/3) is not equal to cos(5X/6)+cos(pi/3)

Answer 17

3cos***
