expand (3cos(x))/((1-sin(x))^2)

expand

\frac{3 cos ( x )}{( 1 - sin ( x ) ) ^{2}}

\frac{3 cos ( x )}{1 - 2 sin ( x ) + sin ^{2} ( x )}

Solution steps

\frac{3 cos ( x )}{( 1 - sin ( x ) ) ^{2}}

(1 - sin (x))^{2} = 1 - 2 sin (x) + sin^{2} (x)

= \frac{3 cos ( x )}{1 - 2 sin ( x ) + sin ^{2} ( x )}

(7 + e^{- 3 t})^{2}

\frac{d ^{2}}{d x ^{2}} ((y (x, s)) (c \cdot e^{2 x} + s \cdot x e^{2 x}))

(e^{2 x} + e^{3 x})^{2}

\frac{2 ( - x - 4 )}{( x - 2 ) ^{4}}

(x + 4) (2 x + 3)
