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

If tan theta=(sin alpha- cos alpha)/(sin alpha+cos alpha) , then:

If tan theta=(sin alpha- cos alpha)/(sin alpha+cos alpha) , then:

If tan theta=(sin alpha-cos alpha)/(sin alpha+cos alpha) ,then theta is

If" " tan theta = (sin alpha - cos alpha)/(sin alpha + cos alpha),"prove that",2 cos^(2) theta = 1 + sin 2 alpha.

(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

(sqrt2 - sin alpha - cos alpha )/( sin alpha - cos alpha)=

If tan theta=(sin alpha-cos alpha)/(sin alpha+cos alpha), prove that 2cos^(2)theta=1+sin2 alpha

If tantheta = (sinalpha-cosalpha)/(sinalpha+cosalpha), then (A) sin alpha-cos alpha=+-sqrt(2) sin theta (B) sinalpha+cosalpha=+-sqrt(2) cos theta (C) cos2theta=sin2alpha (D) sin2theta+cos2alpha=0

underset is If tan theta=(sin alpha-cos alpha)/(sin alpha+cos alpha), then sin alpha+cos alpha
