Hi, from the question given that here we need to use this graph to find the sine function.
00:05
The general form of the sine function will be y is equal to a times sine of b times x minus d plus c.
00:13
So first we need to find the value of a.
00:15
A is nothing but the amplitude.
00:17
Amplitude is nothing but the half of the difference between the maximum and minimum.
00:21
So from this, so here it is given that the maximum value is 5 and the middle value is 2.
00:31
So this is 3, 4, 5.
00:34
Similarly, this is 2 means positive 1, 0 and negative 1.
00:40
So that half of the difference between the maxima and minima.
00:46
So it is 5 plus 1 divided by 2 which is equal to 3...
