We have been given y is equal to 4 sign of 1 by 4 x plus 5 by 8.
00:08
This is the question.
00:10
Now we have to find out the amplitude.
00:12
So, amplitude is actually the product multiplied with the sign or the cost term.
00:17
We can also say that if sign belongs from minus 1 to 1, 1, why would belong from minus 4 to 4 closed.
00:24
Therefore, we will be saying the amplitude is the maximum displacement from the mean position, which will in turn give you 4 as the answer.
00:33
We have to find out the period of the function.
00:35
We know that the period of sine of n theta, where n is the coefficient of theta, or you can say that, or you can say that a sign of nx is given as 2 pi by n...
