No. 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.
