" 12.यदि "tan theta=sqrt(2)" - 1,तब सिद्ध कीजिए कि "cot theta=sqrt(2)+1

यदि triangleABC में (If इन triangleABC), a = (1)/(sqrt(6)-sqrt(2)), b = (1)/(sqrt(6)+sqrt(2)), C = 60^(@) तो सिद्ध कीजिए कि (Prove that) c = (sqrt(4))/(2) .

If (sin theta + cos theta )=sqrt(2) cos theta , show that cot theta =(sqrt(2)+1).

If (sin theta + cos theta )=sqrt(2) cos theta , show that cot theta =(sqrt(2)+1).

" 11."tan theta-sqrt(3)cot theta+1=sqrt(3)

If tan theta+tan2 theta+sqrt(3)tan theta tan2 theta=sqrt(3) then

If cosec theta=b/a , then (sqrt3 cot theta+1)/(tan theta+sqrt3) is equal to : यदि cosec theta=b/a , (sqrt3 cot theta+1)/(tan theta+sqrt3) का मान क्या होगा ?

tan theta=-(1)/(sqrt(3)),sin theta=(1)/(2) and cos theta=-(sqrt(3))/(2)

If tan theta = sqrt2-1 then tan (2theta)=1 .

If tan theta + tan 2theta + sqrt(3) tan theta tan 2theta = sqrt(3) then theta =
