Okay, so we have the function here, y is equal to 3 times sine of x plus pi over 2.
00:06
Okay, so here again, remember, our amplitude is given by the apt value of a.
00:12
The period is 2 pi over b.
00:14
Phase shift is given by d, and the vertical translation is given by c.
00:21
If we have our function in the form y is equal to c plus a times sine of b times x minus d.
00:27
So we can rewrite this as, as y is equal to 3 times sine of.
00:36
Well, instead of x plus pi, it's right, right this as x minus a negative pi over two.
00:44
Okay, and now we again have it in the form, um, y is equal to c plus a times sine of b times x minus d...
