It has been many years since i did integrals and I simply do not remember- need this for probability though.
If i am intergrating from x=.25 to x=.75 does the .25 go on the bottom and .75 on top- then once i integrate the equation, i put in the values for x and then i add them or subtract them? I dont remember this part- what comes first and if i add them or subtract them.
Int 4x^3 from .25 to .75
4* 1/4x^4=x^ from .25 to .75
.25^4 then is it + or - .75^4 and which one goes first, the .75 or the .25?
I know this is probably the silliest question ever.
