if sin(theta+alpha)=cos(theta+alpha) then tan alpha

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

If sin(theta + 3alpha) = 3sin(alpha - theta) then tan theta in terms of tan alpha is ______.

If sin theta = nsin(theta +2alpha) then tan(theta + alpha) =

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

cos ( theta + alpha)* cos ( theta - alpha) + sin ( theta + alpha) * sin (theta - alpha )=
