Re: area
Hi Julieeeee;
Is the purple shaded area what you want?
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

That is correct and nice and simple.

Re: area
What about tangent touching graph of
at a pointI get
And also...
But wolfram alpha says
Why is that so?

Re: area
Hi Julieeeee;
I am getting that for a tangent also. How did you get yours?
For that integral, Maple gets the first answer too. Might be that an absolute value is wrapped around each term and they have both left it out...
When I do it by hand I do not get Alpha's answer either.

Do you get my answer?

Re: area
Hi;
Have you seen an implicit plot of that equation?
Yes, I get your answer when I do the integration.

Re: area
The tangent problem? No I used geogebra to get the tangents for me. But when I look at the graph I am not so sure of the answer we are all getting.
Question: Are you satisfied with your tangent line?
