Things we learned in this unit

There are 2 major problems in Calculus---Tangent problem and Area problem.

In tangent problem, it includes tangent lines and secant line. we can find only 1 point in tangent line, the equation is y=mx+c, m can not be found. For secant line, we can find 2 points in the figure. As for area problem, it's about integral calculus. The equation we knew for area problem is A= lim An (n is infinitive), as n gets bigger, An became closer to the area A.

Besides that, in AP Calculus class, we also learned lots of things that are very important for us. We knew that we should have positive attitude in our daily life no matter how worse the life is, which will help us in the future. And other important thing we learned from this class is we should think out of box, which means we should think from different prospective and be creative. So I believe that with these things we learned in class, we can better challenge ourselves and be successful.
