erweitern (-1+cos(x))/(((1-cos(x))^2+sin^2(t)))

Lösung

erweitern

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

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

Schritte zur Lösung

(1 - cos (x))^{2} + sin^{2} (t) : 1 - 2 cos (x) + cos^{2} (x) + sin^{2} (t)

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

e x p an d (x^{2} + y^{2}) (e^{x y} x y + e^{x y})

e x p an d \frac{( ( p - 1 ) ^{2} )}{p}

e x p an d \frac{64}{( s ^{2} + 1 ) ( s + 8 )}

e x p an d 2 (m + 2 = 22)

e x p an d e^{\frac{z ( 4 t - 4 x )}{- t - t ^{2} + x + x ^{2}}}
