Well another week down and its getting closer and closer to graduation. This week we did more with AP tests.


The steps to substitution are:
1. Find a derivative inside the interval
2. set u = the non-derivative
3. take the derivative of u4. substitute back in

Rieman's sums
LRAM- left hand approximation delta x[f(a)+f(a+delta x)+...f(b)]
RRAM- right hand approximation delta x[f(a+delta x)+...f(b)]
MRAM- middle approximation delta x[f(mid)+f(mid)+...]
Trapezoidal- delta x/2[f(a)+2f(a+delta x)+2f(a+2delta x)+...f(b)]

The steps for taking and implicit derivative are:
1. take the derivative of both sides
2. everytime the derivative of y is taken note it with dy/dx or y'
3.solve for dy/dx

One of my biggest problems is doing some of the math on the non-calculator portion that causes simple errors in my math.
