GRAPHS ON THE GO: MOD effect -2

In this post we will learn what happen when we apply modulus at y.

Now lets begin.

Lets take an example which is y = sinx and | y | = sinx

  

As we did earlier the second graph must break into two section.

1. y = sinx for y>=0

2. -y = sinx for y<0

lets see how how 1 and 2 conditions look-

On merging both graphs we get-

Coming to the point that in this we need to make two conditions as mentioned above and make them separately and then join them.

If we want to do that directly the easiest way out is to remove everything everything in negative y region and replicate the graph of positive y region down there in the negative y portion, this may become clear by following animation-

Now lets see some more examples-

| y | = x

| y | = lnx

Stay Tuned for the next post.
