can someone help me intergrate this step by step
ah i see i got 2 for a answer with that sub. and it is right, thanks, you are brillant.
my only question to that is.. how would u know to sub U in for the whole (3-x)/2.. to me that kinda seems strange cause once u sub u for that, there is nothing really left!, and when u take there derivative of U to get du, u dont see a -1/2 or anything anywhere to relate it to.. so i guess my question summ'd up is, how do u know to sub U as 3-x/2?
but still what about 3-x over 2 makes it a linear function.. how would someonelike me (who isnt so great at math) know to just make u = 3 -x /2.. cause if i didnt come to this forum i d be tryin intgration by parts, u = 3- x, partial fractions all kinds of wastes of time..
