Question

Identify the amplitude and the period of the function c(x) = 3cos (x + π).

Answer 1

amplitude =3
period=2pi/1
=2pi

Answer 2

thank you i really appreciate how did u get it iam takin trig online and iam strugglin?

Answer 3

so the amplitude is the number infront of the trig function, in this case cosine
even if its is 3 or -3 the amplitude is still 3
the period is 2pi divided by the number multiplied by x, in this case, 1x, so 1 except for tangent and cotangent in which it is 1pi divided by the number multiplied by x

Answer 4

so if i were to do a problem like this Identify the amplitude and the period of the function
q(x) = -sin (π/2 x).
the amplitude would be -1 and pie/2

Answer 5

amplitude is 1
period is 2pi/2= pi
