Perhaps you meant sin(x)+x^2?

- sketerpot 17y agoNo. Just use the product rule. The derivative is x^2 cos(x) + 2 x sin(x) Finding derivatives is actually really easy. There are just a few simple rules you have to apply deterministically to any problem, and the answer will pop out.
- jrockway 17y agoI think his point was to suggest a simpler question. Do you really think most "entry-level office workers" remember the product rule?
- sketerpot 17y agoI believe the whole point of proposing a calculus question was that most entry-level office workers won't be able to answer it.
- jrockway 17y agoAs I mention above, I bet they wouldn't be able to answer an even simpler question. Requiring application of product rule "raises the bar" a bit too high.
- jrockway 17y agoI'm not sure why this is modded down so far, as it raises a good point. If you ask the average entry-level office tech to differentiate x^2 with respect to x, it is likely that they will not even know that. Throw in the product rule, and all bets are off. (I am embarrassed to admit that I had to quickly look at MathWorld to make sure I hadn't misremembered it.)
