Question

please help me solve

Answer 1

45 degrees since

Answer 2

Pi/4

Answer 3

can you please explain to me how you got that?

Answer 4

notice that \[\frac{ \sqrt{2} }{ 2 }=\frac{ 1 }{ \sqrt{2} }\]
which we remember from the triangle

Answer 5

simple \[\sqrt{2}/2=1/\sqrt{2}\]
it will affect only if the value is out of range

Answer 6

what are you talking about? confused the answer is pi/4 how did you get that?

Answer 7

can u answer my simple questions...........?

Answer 8

which is?

Answer 9

do u know about domain and range of sin^-1(x)???????

Answer 10

no

Answer 11

thats y u r getting confused in values

Answer 12

do u want me to tell about it right now:)

Answer 13

i just want to know how you got that answer

Answer 14

sin x is basicaly defined for all values of x but -1<sin x<1 happens always when we define sin^-1 x it is a inverse or we can say just opposite to the sinx which is defined for -1<x<1 and answer lies anywhere so a basic principle regien is defined and all other area is called general area so we knoww that sin 45 = 1/\[\sqrt{2}\] so sin -1 x = 45 degree or pi/4 radians in principal region.............k

Answer 15

:)

Answer 16

thank u first time i feel that i deserve it.lolz:D
