Not too easy. Not too difficult.
Course Overview:
I recommend taking an online free course at Coursera.com to anyone who can. What has one to lose? Calculus I, the only class I have taken through this website, is taught through videos that were posted some time ago. One needs to learn it through just the videos and the text, which is fairly easily found and downloaded free in pdf format. It is perfect if you are brushing up, or if you are good at learning from a text and one very good, clear explanation of each piece of the 'puzzle' on a video.
Course highlights:
Calculus I, which I have passed at another college and which, like I say, is free on Coursera.com, is now much more familiar to me than it ever was. This course entails derivatives and antiderivatives, which, if you are prepared, are not difficult to grasp. Once you have a good handle on algebra and trig, dive in! You'll learn what derivatives and integrals (antiderivatives) are, and you will get a great handle on how to use them! They are used for all kinds of things, like area, volume and slopes of curves, among tons of other applications. If you're looking to do any kind of technical, engineering, mathematical or science-related studying or work, go for calculus and look forward to understanding the world of math like never before.
Hours per week:
3-5 hours
Advice for students:
You will need to have a good handle on algebra, and to understand the trig functions. This class is not timed, which helps if you want to go at your own pace. I highly recommend learning things online before starting at a brick-and-mortar college or university.
