erweitern (3cos(x)-2)(tan^2(x)-1)

Lösung

erweitern

(3 cos (x) - 2) (tan^{2} (x) - 1)

3 tan^{2} (x) cos (x) - 3 cos (x) - 2 tan^{2} (x) + 2

Schritte zur Lösung

(3 cos (x) - 2) (tan^{2} (x) - 1)

Apply FOIL method

(3 cos (x) - 2) (tan^{2} (x) - 1) : 3 tan^{2} (x) cos (x) - 3 cos (x) - 2 tan^{2} (x) + 2

= 3 tan^{2} (x) cos (x) - 3 cos (x) - 2 tan^{2} (x) + 2

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

e x p an d (- \frac{1}{2} x + \frac{11}{2})^{2} - (3)^{2}

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

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

e x p an d x (3, - 1) y (0, - 5)
