Curve Sketching (graded) |
Given the function: f(x) = 5x3 - 125x
Take turns determining the following.
- Domain and Range;
- X and Y Intercepts;
- Maxima and Minima;
- Increasing/Decreasing Behavior;
- Concavity; and
- Point(s) of inflection.
Be sure that you explain how you determined each part.
Also, if you have other questions that you would like me to address, post them here.week 4
Trigonometric Functions (graded) |
Trigonometric functions are some of the most important functions that you will explore. Remember that they are periodic, so they have many real-world applications in studying various kinds of waves and frequencies. Here are some questions that we will address. Please post answers in this thread.
- What are the formulas for the derivatives of the trig functions?
- How do we use them to find derivatives of more complex functions involving trig forms?
- How can we use the trig identities to rewrite functions so that we can apply the basic formulas?
- What are real-world applications for trig functions, particularly those that come from your program?
- Explain how you can use the derivative to explore these applications.
Please feel
