First Link:
1st problem- Looks like a trig identity. You should have a list of trig identities in the back of your book. I might be mixing up calc I and calc II though. It's been a while, and I don't have my book on me.
2nd problem- combine 2x and sqrt(x) (or 2x^3/2) and then do product rule.
Second Link:
1st problem- Can be re-written as (5e^x)*(sec(x)). Product rule that. In the second portion, distribute ln(x) to 3x and x^4*sinx. Prepare for more product rule bukakke.
2nd problem- treat secx^2 as f(x) and (e^2x + 1)^1/2 as g(x). Moar product rulez! Solution should be the derivative over the original equation since it's a ln derivative.
Again I must emphasize that it's been a while since I took Calc, so I might be off on something. Then again, if I don't remember it, my TI-89 usually does lol.
