know the general formula for
if, u can't use direct formula.....u can substitute...
first u need to divide by b to be able to use it...
I've understood that much. What to substitute?
A better question: what general logic (other than having seen this problem before, which won't be of help in the future) do I use when deciding what to substitute?
It seems with the x^2 the cos^2+sin^2=1 identity may be useful.
when there is + ans a square term.. u think of 1+tan^2x = sec^2 x
so that u can substitute here s= tan
OK- I've got that integral- is there any general rule for deciding how to substitute, or is it mainly intuition?
seen my tutorial, right ? i've given table of substitution there. .
but yeah, that comes with practice....
Tables are artificial, only useful for engineers. But thanks.
