If ` sin ( theta + alpha ) = cos ( theta + alpha )`, then ` tan theta =`

If sin (theta + alpha ) = cos ( theta + alpha), prove that tan theta =(1- tan alpha )/(1 + tan alpha )

If a* cos ( theta + alpha ) = b cos ( theta - alpha ) , " then " ( a+ b) tan theta =

If sin(theta + alpha)=cos(theta+alpha), then the value of tan theta is: a.    1-tan alpha b.    (1-tan alpha)/(1+tan alpha) c.    1+tan alpha d.    None of these

If sin(theta+alpha)=cos(theta+alpha) then the value of tan theta is

If sin theta =3 sin ( theta + 2 alpha), then the value of tan (theta + alpha) + 2 tan alpha is

If sin theta = 3 sin ( theta + 2 alpha) , then the value of tan (theta + alpha ) + 2 tan alpha is

If ( sin ( theta + alpha ))/( cos ( theta - alpha ))=(1- m)/(1+m) , " then " tan"((pi)/4- theta )=

General term ( sin^2 theta = sin^2 alpha , cos^2 theta = cos^2 alpha, tan^2 theta= tan^2 alpha)

Simplify be reducing to a single term : cos (theta + alpha ) cos ( theta - alpha ) - sin ( theta + alpha ) sin (theta - alpha).
