These are the two last problems I'll bother you with for a short while (I love this forum, I'll definitely stay on and hopefully be able to contribute in the future).
1. The problem statement, all variables and given/known data
Problem 1:
(##-x^2##-1)sin2x > 0 , xe[0,2[itex]\pi[/itex]]
Problem 2:
##2^{-x^2+x+2}## < 4
2. Relevant equations
3. The attempt at a solution
For the first problem:
(##-x^2##-1)sin2x > 0 , xe[0,2[itex]\pi[/itex]]
Since x is an element within a positive boundary, can I write the problem as:
sin(2x) ≤ 0
Why, or why not?
Other than that, I need to refresh my knowledge on solving inequalities.
Any help or input is appreciated while I attempt to gather more info.
