Okay, so as i'm super nervous that wednesday is the AP test, i'm going to say a few things i think i'm actually getting the hang of.

But first, when you figure out the lram, rram, and tram from a graph..which way do you draw the thing? taht's really confusing, but hopefully someone knows what i mean.

So, when you're given a table on free response, don't freak out, i finally know what to do! It means sometime in that question you are going to have to find slope. and to find slope, you do the y-values - y-value divided by x-value - x-value. SUPER EASY POINTS.

Now, it'll prob ask you tangent line since it just made you find slope..and taht's easy too, it'll be the points you just used!

Also, when they give you a wierd graph, all you have to do to find area is divide it into shapes and add all the areas. And if it asks you for total distance traveled, its the absolute value of all the areas added together. And, if it asks where someone turned around, or something like that, its teh negative parts of the graph.

Now, the question i always get wrong, when it says something about a graph's volume being area perpendicular to the x-axis, squared...all you do is solve the equations for x and then plug them into the volume formula and square the whole thing.

As the AP comes closer i get more nervous and anxious at the same time. I just hope i pass! And i hope everyone else does too, of course!
