Question

Find the amplitude and the period of b(x) = -5sin(Πx).

Answer 1

How do I solve this ?

Answer 2

we use formula
period = 2pi / |B|

Answer 3

that is one ugly pi

Answer 4

for general sinusoidal
y = A sin (Bx-C) + D

Answer 5

looks ok to me

Answer 6

\[-5\sin(\pi x)\]

Answer 7

\[-5\sin(\Pi x)\] either way i guess

Answer 8

oh, its a capital Pi

Answer 9

yeah

Answer 10

im not familiar with the latex stuff
but i notice cant use alt 233 , and other alt commands

Answer 11

@mashlyashela

period = 2pi / pi , in your case. so period = 2 . do you agree?

Answer 12

Oh okay. So amplitude is 5 and the period is 2 ? @perl
