If `(sin(theta+A))/(sin(theta+B))=sqrt((sin2A)/(sin2B))` then `tan^2 theta` is

If sin theta+csc theta=2, then the value of sin(theta)/(16)sin(theta)/(8)sin(theta)/(4)sin(theta)/(2)sin2 theta is 1 b.(1)/(sqrt(2)) c.-(1)/(sqrt(2)) d.0

sin4 theta can be written as (a) 4sin theta(1-2sin^(2)theta)sqrt(1-sin^(2)theta)(b)2sin theta cos theta sin^(2)theta(c)4sin theta-6sin^(3)theta(d) None of the above

If sin theta-cos theta=sqrt(2)sin(90^(@)-theta), then tan theta=

If sin theta+cos theta=sqrt(2) and b=(sqrt(2)(sin theta+cos theta))/(sin theta cos theta), then 'b'is equal to

If sec theta (cos theta + sin theta) = sqrt2 , then what is the value of (2 sin theta)//(cos theta- sin theta) ? यदि sec theta (cos theta + sin theta) = sqrt2 है,तो (2 sin theta)//(cos theta- sin theta) का मान क्या है?

Prove that (2 sin theta - sin 2theta)/(2 sin theta + sin 2theta) = tan^2\ theta/2

tan theta= A) (sqrt(1-sin^(2)theta))/(sin theta) , B) (1)/(sec theta) , C) (sin theta)/(sqrt(1-sin^(2)theta)) D) (1)/(sqrt(1+Cot^(2)theta)

(sin 2 theta)/(sin theta)-(cos 2 theta)/(cos theta)= A) sec theta B) tan theta C)1 D)2

If |{:(1+cos^2 theta, sin^2 theta, 2sqrt3tantheta),(cos^2 theta, 1+sin^2 theta, 2sqrt3tan theta),(cos^2 theta, sin^2 theta, 1+2sqrt3 tan theta):}| =0 then theta may be :
