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

Statement I : If m cos(theta+alpha)=n cos (theta-alpha) then tan theta.tan alpha=(m+n)/(m-n) Statement II : If (sin(alpha+beta))/(sin(alpha-beta))=(a+b)/(a-b) then tan alpha.cot beta=(a)/(b) Which of the above statements is correct ?

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

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

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

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

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