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

sin 2 alpha - cos 2 alpha tan alpha =

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

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

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

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

If sin alpha+cos alpha=(1)/(5) then tan((alpha)/(2))
