Question

WILL REWARD!
What are the period and amplitude of the function y=2sin4 theta?

A. pi/2 and 2
B. pi and 4
C. pi/2 and 4
D. pi/2 and 1

Answer 1

in
\(y= A \sin (wt)\)
A is the amplitude!

so here, whats the amplitude ?

Answer 2

\(period = T = 2\pi/w \)

Answer 3

What is the maximum value of sin theta for any value of theta ?

Answer 4

Find out the max value(amplitude) and you'll have ur answer...

Answer 5

The amplitude would be 2

Answer 6

correct!

Answer 7

so which option ?

Answer 8

The correct option would be A.

Answer 9

yes :)
