end this torture fast pls

Stress ar!! I skip inverse trigo, cos i know hw to apply the formula alrdy. The most problematic chapter is the freaking extrema and critical point.. Argh!! And my derivative of expo and log is like freaking messed up. Though log i'm on my way to fully understanding. i know my first order derivative, just that when 2nd derivative is added in, i got mixed up alrdy. damn it. I know hw to find critical values, yes i know. I know how to draw for the first derivative graph. Critical points for max and min pts, slowly.. still the 2nd derivative test i DUNNO!! argh.. I dunno wad i am typing. My brain is gg to explode. Regret sleeping in class and not paying attention.
