Question

What is the midline of 2cos4x

Answer 1

do you know what a midline is?
or where it is written in an equation?

Answer 2

no that’s why I’m struggling on

Answer 3

What*

Answer 4

I thought it was 2 but I think it’s wrong

Answer 5

okay, the 2 is the amplitude, in an equation when it's _cosx + _
the first _ is amplitude
the second is _ is midline
in this case, because there isn't something added, the midline is 0

Answer 6

Is the midline always zero?

Answer 7

no
only if there is nothing added on
if it was cosx -2, the midline would be at -2
if it was cosx +9, it would be at 9

Answer 8

Ohhh okay thank you

Answer 9

yw

Answer 10

Do you also know how to find the length of an equation like where the line stops

Answer 11

yk, bro, i'm also taking algebra 2/trig rn lmao
i'm right in the unit doing sinusoidal functions, and tbh, i suck at it
but the function has no limit in domain so~

Answer 12

oh alright well thank you!

Answer 13
