We started off class today by getting into groups and correcting our midterm multiple choice.
It's important to remember the product rule and the chain rule. Also, looking at the answers sometimes can be helpful in figuring out whether or not a calculator is needed to answer the question, and in figuring out what work is really necessary.
Next, we went over the free response questions. Again, it's important to remember wording and proving things with calculus. Also, number lines are not counted as a justification, instead you have to use words in your conclusion. To get the marks you have to write out an answer, being careful about using ambiguous pronouns. There are 9 marks per free response question. Remember to verify and explain to get all the points. Also, be careful to follow the instructions and show all you work when the directions ask for it, and answer exactly what the question is asking.
Finally, we took a quiz which was a free response question.
Here's a link about finding derivatives of inverse functions, which is something we've had on homework and a test, and the midterm, but is still something we're finding a little tricky. http://www.analyzemath.com/calculus/Differentiation/derivative_inverse.html
