b ) (sin^2 alpha * (1 + cos alpha))/(cos^2 alpha * - Dicamon

Question

b ) (sin^2 alpha * (1 + cos alpha))/(cos^2 alpha * (1 + sin alpha)) = (sin alpha + tan alpha)/(cos alpha + cot alpha)

Answer

a ( ) cos alpha + (cos 2)/(sin alpha); =sin alpha (cos alpha+1) cos alpha; = sin alpha*(cos alpha+1) cos alpha* cos alpha(sin alpha+1) * sin alpha; = sin^ 2 alpha(1+cos alpha) cos^
