Write an equation for the graph above.
00:04
So here we have a graph of a cocicant, which is very similar to the graph of a c -cat.
00:15
The difference being the location of the peaks here.
00:20
So we know that our cosicant will write as y equal to some amplitude a times the cosicant of kx plus b.
00:43
All this plus c where c corresponds to the offset of our graph along the y -axis.
01:17
So we see clearly that our graph is not, these peaks here, are not symmetric about the y -equal -to -zero axis, so we're going to have an offset here in c.
01:33
So normally, a cosicant has its peaks ranging between plus and minus one, but here to be also mindful of the amplitude a.
01:59
So to make these peaks symmetric about the origin, we're going to need a negative offset of minus three units.
02:22
Oh, excuse me, not three, two, plus two units.
02:29
So one plus two is three and minus five plus two is minus three...
