What do you like about this subject?
I was in a coma back in 1986; while in the hospital and before I could walk or talk, they told me I was assisting a nurse with math. I even enjoy doing it for fun ... don't you?
What do you still hope to achieve/learn in this field?
Doing even more mathematics. Maybe somebody wants me to do this for work, but until then ...
Something interesting about this subject that others may not know:
The natural log of e is 1 [ ln(e)=1 ], but did you know that e=2.71828182845905... or that pi, the usual 3.14, is really 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 58209 74944 59230 78164 ... and so on ...
Something controversial or provocative about this subject
Some people have controversies in statistics. When they say average, there are three different ways to do it. Some are interested in (max-min)/2, some are interested in the midway point, and some are actually interested in the true average (add 'em up and divide by n). This might not actaully be controversial, but at least you have read something here that is done in different ways.

a) After 4 years, the value will have gone up by $120, so it will be worth $820. To get an equation, just take that value and subtract of $30 times the years. Here, t would be 0, 1, 2, 3, or 4, and the

Yes, the attached graph made the 1st answer very clear. PART A By looking at the graph, non-zero terms could be at x=0.5, 2.2, 4.8, etc. That is, anything that is 2n + x where n is an integer and

starting mileage 1200 ending mileage 1290 gallons used 6 mileage = (end - start)/used = (1290-1200)/6 = 90/6 = 15. For another table, just change the value to something else. It would be good to
2012-01-05 Calculus:
Since profit is revenue minus cost, we have p(x) = r(x) - c(x) = [x²/(x²+1)] - [(x-1)³/3 - 1/3]. At least, that's what c(x) looks like, right? Now taking out the brackets, we have p(x) = x²/(x²+1)
2011-12-21 calculus:
If the curve is y = 2 - cosx/sinx, then that is y = 2 - ctnx. However, I believe it really to be y = (2-cosx)/sinx. If this is so, it still resembles the ctnx curve in that it has undefined points
