\[\sin x + \cos x - \sqrt{2}\sin x = 0 then value of tanx ^{2} + cotx ^{2} is \]
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):
\(tanx=-\frac{1}{1-\sqrt2}\)

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