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

if tan beta=(n sin alpha cos beta)/(1-n sin^(2)alpha) then prove that tan(alpha-beta)=(1-n)tan alpha

if tan beta=(n sin alpha cos beta)/(1-n sin^(2)alpha) then prove that tan(alpha-beta)=(1-n)tan alpha

If tan beta=(n tan alpha)/(1+(1-n)tan^(2)alpha), then tan(alpha-beta)=(1)(1+n)tan alpha(1-n)tan alpha( ii) -(1+n)tan alpha( iv) -(1-n)tan alpha

If tan beta =(n tan alpha )/(1+(1-n) tan^(2) alpha ) , then tan(alpha-beta)=
