solve the question>???

OpenStudy (anonymous):

\[\sin x + \cos x - \sqrt{2}\sin x = 0 then value of tanx ^{2} + cotx ^{2} is \]

OpenStudy (anonymous):

after =0 then value of tan x sq .......

OpenStudy (***[isuru]***):

first divide the whole equation from sin x

OpenStudy (***[isuru]***):

it will leave only cot x.. u can find the value of cot x then

OpenStudy (ikram002p):

\(tanx=-\frac{1}{1-\sqrt2}\)

OpenStudy (***[isuru]***):

then divide the whole equation again from cos x ... it will give u the value of tan x

OpenStudy (***[isuru]***):

square the values separately and add them

OpenStudy (anonymous):

guys the option are A)8 B)6 C)1 D)1/2

OpenStudy (***[isuru]***):

\[\sin x + \cos x = \sqrt{2}\sin x\]\[\frac{ sinx }{ \sin x } +\frac{ cosx }{ sinx } = \frac{ \sqrt{2}sinx }{ sinx }\]\[1 + \cot x = \sqrt{2}\]\[\cot x = \sqrt{2} - 1\]

OpenStudy (***[isuru]***):

\[sinx + \cos x = \sqrt{2}sinx\]\[\frac{ sinx }{ cosx } + \frac{ cosx }{ cosx } = \frac{ \sqrt{2}sinx }{ \cos x }\]\[tanx + 1 = \sqrt{2} tanx \]\[tanx ( 1 - \sqrt{2} ) = -1\]\[tanx = -\frac{ 1 }{ 1 - \sqrt{2} }\]

OpenStudy (***[isuru]***):

now square then and add ... can u do that ?

OpenStudy (anonymous):

i know you can do it why stop one step closer to victory

OpenStudy (anonymous):

NEVER GIVE UP

OpenStudy (***[isuru]***):

it's u who should solve this... not me :P

OpenStudy (***[isuru]***):

i will help u

OpenStudy (anonymous):

i know you are good boy and good boys never give up

OpenStudy (ikram002p):

ive got 6 wbu ?

OpenStudy (***[isuru]***):

i dint solve it yet... gimme a minute

OpenStudy (anonymous):

and you are write my dear

OpenStudy (anonymous):

i got it

OpenStudy (anonymous):

the sum not the soln

OpenStudy (anonymous):

but never mind i will solve it

OpenStudy (***[isuru]***):

huh?
