i hope u mean sin-1x
if -1<x<0 den sin-1 x =?
a dice is rolled 4 times d probability of getting a larger no dan d previous no each time is?

Total no. of possibilities = 64
if first is 1 then the no. of ways of getting a larger no dan d previous no each time i 5*4*3 = 60 ways
If first is 2 then then the no. of ways of getting a larger no dan d previous no each time is = 4*3*2 = 24
If first is 3 then then the no. of ways of getting a larger no dan d previous no each time is = 3*2*1 = 6
If first is 4 or 5 or 6 There is no possibility
Therefore the probability is 90/6*6*6*6 = 0.0694 = 0.069
Both the answers are rite it is the way thing in a different manner
no dude in inverse functions.......u got to know principal domain....
ur answer (pi/2,pi) isn't in principal domain of sin-1x
i hope u get the point...
dice q
4 throws
chose any 4 nos and they can be in asc order in only one way
so fav case = 6C4
total case = 64
so probability = 15/64 =5/432
frnds im not asking about domain but im asking weder it is Cos-1 √1-x2
or ∩-Cos-1 √1-x2
plz tell me

hmm.. you can think it like this
sin -1x will be -ve
also it will be in -pi/2 to 0
so cos inverse should also be -ve
but π-Cos-1 √1-x2
will be +ve and greater than zero....
so what should you try to do?
