quarter 3 benchmark Flashcards
sine starts on the
midline
cosine starts on
up amplitude from the midline
sine reg go
up
sine reflection go
down
cosine reg go
down
cosine reflection go
up
sine wave is
snake
cosine wave is
cup
sine (reg) graphs like
stay, up amp, stay, down amp, stay
sine (reflection) graphs like
stay, down amp, stay, up amp, stay
cos (reg) graphs like
stay, down amp, down amp, up amp, up amp
cos (reflection) graphs like
stay, up amp, up amp, down amp, down amp
if -cos, what is amplitude
amp is 1, but you go down 1 from midline on start interval
amp can never be
negative

inverse
for law of sine and cosine: what do you use when you need to solve for side
regular
when to use law of sine
when there is opposites
when to use law of cosine
when there are no opposites
