erweitern (tan(x)-sec(x))^2

Lösung

erweitern

(tan (x) - sec (x))^{2}

tan^{2} (x) - 2 sec (x) tan (x) + sec^{2} (x)

Schritte zur Lösung

(tan (x) - sec (x))^{2}

Wende Formel für perfekte quadratische Gleichungen an:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(tan (x) - sec (x))^{2} = tan^{2} (x) - 2 tan (x) sec (x) + sec^{2} (x)

= tan^{2} (x) - 2 tan (x) sec (x) + sec^{2} (x)

= tan^{2} (x) - 2 sec (x) tan (x) + sec^{2} (x)

e x p an d \frac{1}{s ( s ^{2} + 9 )}

e x p an d \frac{2 x ^{3} - 6 x ^{2}}{( x - 2 ) ^{2}}

e x p an d (- e^{- t} sin (t) + e^{- t} cos (t))^{2}

e x p an d cot (x) (cos (x) - sec (x))

e x p an d R (- 4, 3, - 7) y S (0, 3, 0)
