sqrsinx + tanx = 0 sqrsinx =  tanx sinx = tan^2x squaring both sides 1 = 1/cosx dividing both sides by sinx cosx = 1 crossmultiplying x = 0 i am not sure ... .. but i just tried i am also learning trigonometry

sqrt 2sinx + tanx = 0 sqrt 2sinx = tanx squaring both sides we get 2sinx = tan^2x 2 = sinx/cos^2x

sabika, before ppl can help you, they need to understand your question clearly. even now your question is vague... not clear..... is it sqrt2(sin x ) or sqrt(2sin x ) ?

sqrt 2sinx + tanx = 0 sqrt 2sinx = tanx after squaring both sides we get 2sinx = tan^2x or sinx(2sinx/(cos^2x))=0 then sinx=0 or x=0,pi,pi (one part ) the other part may can be obtained from (2sinx/(cos^2x))=0

how did you go from 2sinx=tan^2x to sinx(2sinx/cos^2x0 =0 ?

matricked Group TitleBest ResponseYou've already chosen the best response.0
use tanx=sinx/cosx

yeah so sin^2x/cos^2x =2sinx 2sinxcos^2x=sinx^2 2sinx(1sin^2x)=sin^2x ... am i doing it right?

2sinx cos^2x = sin^2x i have taken this statement from you 2sinx ( 1  sin^2 ) = sin^2x 2sinx  2sin^3 =sin^2x 2sinx  2sin^3  sin^2x = 0 2sin^3 + sin^2x  2sinx = 0 sinx( 2sin^2 + sinx  2 ) = 0
