I dont think we are talking about Pre-Algebra here mate. The number of "stratagems" you can use in a given problem is vast and you need some guidance. Otherwise, you may dont know how to approach some problems or end up in a cul-de-sac

alright so my right triangle looks like pic related.
Ive integrated my function and the answer I get is:
>lnIsec(1/2)+tan(1/2)I.
Itd be easy to just replace sec and and tan by the sides I get in my triangle except the (1/2) inside are bothering me.
Does anyone know how I go?
-Maybe replace them when they are on their form sec(theta) and tan(theta) and then multiply what I get by 1/2?
