"prove that d/dx (xsin^-1 (x)) = sin^-1(x) + x/(root(1-x^2). "xrtzx said:this question is from fitzy ex 26 (d) pg 156
prove that d/dx (xsin^-1 (x)) = sin^-1(x) + x/(root(1-x^2). hence find the primitive of sin^-1(x) and show that: the integral between .5 and 0 (sin^-1 (x)) = (pi/12) + (root3/2) -1
thnx
actually it's ironic, cause i've never played it.Originally Posted by FinalFantasy
i like it how u always bold my username
hahaha
do u like Final Fantasy- the game?
hahaha, but dun u find it annoying typing all those codes in all the timewho_loves_maths said:actually it's ironic, cause i've never played it.
no i bold or put in italics everyone's nick that i mention in any of my posts as a sign of respect... just something i'm used to. and also so as not to confuse nick's with normal words and phrases, etc... seeing how some nick's are not actually distinguishable from the vernacular.
but in this case, you had priority in posting the solution to this problem, so bolding your name is highlighting my acknowledgement of your antecedent solution to my "tidying-things-up" post
hahaha... why do you think you always win the race to posting up solutions to integration problemsOriginally Posted by FinalFantasy

like having to type [bold /] and stuff
