Post #17

Alright everyone, we have Calculus Exam Packets this weekend to start on our exam which is comming up on monday! I say we all get together!..ha
but anyways, this past week we took a practice AP Exam.
The first portion was without a calculator so we need to know and remember our formulas and how to read graphs.
~remember that an odd function is symetric about the x axis and an even function is symetric about the y axis.
~remember how to solve in order to get an equation of a tangent line:
take the derivative and find the slope then since you need a point you'll plug in the number they give you to the original equation
~in order to find vertical asymptotes set the denominator equal to zero.
~know that when you’re looking at the derivative of a graph and you want to find a graph that is the original, if it’s increasing then you know that it will have to have a positive slope.
~Average value is not the same thing as average speed!...remember is one over b-a times the integral of the equation.
Tuesday we were unable to get to school due to flooding, so we were off!
Wednesday when we came back, we took the second portion of the AP Exam which allowed calculators!
~if you need to find values that the slope of a tangent line is equal to a certain number:
Take the derivative and set it equal to that number when you solving with a calculator go to y = and plug in the equation look at the graph and go to calc zero and guess what they are and you’ll have your answer!
~When you want to find the smallest positive value, plug the equation into y = and then adjust window, go to second trace and maximum guess the left and right then guess what the max should be and they’ll tell you the answer!
~remember if you need to find the integral of something then go to fnInt( and plug in the equation}, X, the number, the other number [that’s at the top and bottom of the integral] and that will give you the answer!
~know if you’re looking at the derivative of the graph, in order to find the maximums, look at the zeros. [and maximums must go from positive to negative]
~remember the equation for average rate of change: f[b]-f[a] all over b-a then plug in using the points they give you and solve!
Thursday and Friday we went over all of the things we had wrong on the practice AP Exam! B-Rob said that we should've got at least 10 questions right.


DO NOT FORGET:
We have the packet for our take home portion of our exam to do! Good Luck to everyone!
