Exercise: Examine graphs of y = a sin (bx + c) for different values of a, b, and c.


Lets begin with the simple case of a, b, c = 1

basic graph

 

playing around with the values of a,b,c will give us a visual of how they change the graph:

Let us first vary a but keep b and c fixed at 1:

a = 2

a=2

a = 3

a=3

a = -2

a=-2

a = -3

a=-3

Notice how a affects the y values of the graph. Also negative values of a will invert the graph across the x-axis.

Observe the animation below has a varying from -5 to 5:

Now let's vary b but keep a and c fixed at 1:

b = 2

b=2

b = 3

b=3

b = -2

b=-2

b = -3

b=-3

Below is the animation of b varying from -5 to 5:

Finally lets vary c and keep a and b fixed at 1:

c = 2

c=2

c = 3

c=3

c = -2

c=-2

c = -3

c=-3

And again we have an animation of c varying from -5 to 5:

Just for funsies look at this crazy graph with a=7, b=45, c=0:

woot
