If sin alpha+cos alpha=sqrt(2)cos alpha then show that tan2 alpha=1

If sin alpha + cos alpha = sqrt2 cos alpha,"show that",tan 2 alpha = 1

If sinalpha+cos alpha=sqrt2 cos alpha then prove that tan 2alpha=1

sin 2 alpha - cos 2 alpha tan alpha =

If tanbeta =(sin alpha cos alpha)/(2 + cos^(2) alpha),"prove that " 3 tan (alpha -beta).=2 tan alpha

Prove that, (sin alpha + cos alpha)/(cos alpha-sin alpha)=tan2 alpha + sec 2 alpha

If tan beta = (n sin alpha cos alpha)/(1-n sin^(2) alpha), "show that", tan (alpha - beta) = (1 - n) tan alpha.

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

If 0

If tan beta=(n sin alpha cos alpha)/(1-n sin^(2)alpha), show that tan(alpha-beta)=(1-n)tan alpha
