A Bounded Area (def Int) with log base 4 (5.5 p359 #81)
This one has u substitution a a conversion from base 4 to bas e, confirming with the TI-84
An Indefinite Integral with Exponents (5.5 p 359 #76)
This includes u-substitution, and an exponential function in base 2
Proving an old Compounded Interest Formula with L'Hôpital's Rule (5.6 p371 #90)
We demonstrate the ln technique as well as makeing a product into a ratio so you can use L'Hôpital's Rule.
The Derivative of an Inverse Function (5.3 p340 #67)
The derivative of a inverse function is the reciprocal of the derivative of the inverse function. Be mindful of the exchange of values (x,y) to (y,x) with inverse functions

Using L'Hôpital's Rule on an e^x Function
Here I explain how to use your school email address and your teachers 6 digit teacher (or access) code) to get started with DeltaMath.com
Use limits to test Continuity! We check if the function exits, the limit from left and right exist, and they are all match!
