erweitern-(8sin(θ))/((2-cos(θ))^2)

Lösung

erweitern

- \frac{8 sin ( θ )}{( 2 - cos ( θ ) ) ^{2}}

- \frac{8 sin ( θ )}{4 - 4 cos ( θ ) + cos ^{2} ( θ )}

Schritte zur Lösung

- \frac{8 sin ( θ )}{( 2 - cos ( θ ) ) ^{2}}

(2 - cos (θ))^{2} = 4 - 4 cos (θ) + cos^{2} (θ)

= - \frac{8 sin ( θ )}{cos ^{2} ( θ ) - 4 cos ( θ ) + 4}

e x p an d \frac{4 s + 1}{s ( 2 s + 1 ) ( s + 1 )}

e x p an d \frac{( x - 0 ) ( x - 1 ) ( x - 4 )}{- 4}

e x p an d (\frac{1}{x ^{2}} + y^{3})^{4}

e x p an d (1 + 2 x^{3}) e^{x^{2}}

e x p an d (x - \frac{2}{x})^{15}
