At.......` tantheta` is not defined,
`(A) theta=45^@`
`(B) theta=0^@`
`(C) theta=90^@`
`(D) 0 lt theta lt 45^@`

If sin theta = sqrt(3) cos theta, 0 lt theta lt 90^(@) , then theta is equal to .

if theta = 45^0 then tan^2 theta + 1/(sin^2 theta)

For what value of theta , is (tan theta + cosec theta) = 2.5 where 0 lt theta le 90^(@) ?

If (sin 3theta)/(cos 2theta)lt 0 , then theta lies in

If tan theta+cot theta=2 then value of tan^(n) theta+ cot^(n) theta(0^(@) lt theta lt 90^(@) n is an integar) is यदि tan theta+cot theta=2 , तो tan^(n) theta+cot^(n) (0^(@) lt theta lt 90^(@) एक पूर्णाक है) का मान है

If (cos ^(2) theta - 1) ( 2 sec ^(2) theta) + sec ^(2) theta + 2 tan ^(2) theta = 2 , 0 ^(@) lt theta lt theta lt 90^(@) , then (( "cosec" theta + cos theta))/(( "cosec theta - cos theta)) is equal to :

If "cosec"^(2) theta + 2 cot^(2) theta=10 , then find the value of sin theta + cos theta when 0^(@) lt theta lt 90^(@)
