I've been using splenda all over the place, but now i'm confused the main ingredient for Splenda is Dextrose...isn't that a just double glucose? Which is sugar....so basically Splenda has Sugar?
I know Sucralose is artificial...sugar/sweetener, and isn't digested...but dextrose is..and what is Maltodextrin.
I thought with splenda, i was going to lose weight, but no change, actually i got bigger.

Unfortunately there is a frog sitting in the middle of the creek, who can jump with initial velocity 5m/s in either direction, and swallow the grasshopper in mid-air.

What is minimal initial velocity required to jump over the frog to the other bank of the creek?

I am having some trouble with 2 different trig problems. Can someone lend me a hand?

1.) arcsin [sin Pi/6] (they want an exact answer)

2.) write the following as an algebraic expression.

tan [sec-1 u/5 ] (*the -1 is actually an inverse sine)


I am unable to reach my professor and would really appreciate any help! Thank you!
