Question

Q: Amplitude of y=5 cos x

Please don't just give me the answer I want to learn how to work it out.

Answer 1

i think this might help

Answer 2

sorry if this does not help this is how i leared

Answer 3

Yes this helps! Thank you so much!

Answer 4

ho np

Answer 5

:P

Answer 6

y = A*cos(Bx - C) + D

has the amplitude |A|

you take the absolute value of whatever number is in front of the cosine to get the amplitude

Answer 7

Thank you! :)

Answer 8

y=A cosx
A is amplitude...put different values of A..u would get waves of different amplitudes
