(2 cos (x) - 1) (2 cos (x) + 1)

4 cos^{2} (x) - 1

Schritte zur Lösung

(2 cos (x) - 1) (2 cos (x) + 1)

Apply Difference of Two Squares

(2 cos (x) - 1) (2 cos (x) + 1) : 4 cos^{2} (x) - 1

= 4 cos^{2} (x) - 1

e x p an d 4 (x + h) - 3 - 4 x - 3

e x p an d x^{s i n (x)} (cos (x) ln (x) + \frac{sin ( x )}{x})

\frac{d}{d x} (x^{4} - 2 x^{3} - 4 x^{2} - 5 x + 2)
