Schritte zur Lösung

- \frac{120}{( 3 - 1 ) ^{6}} - cos (3 - 1)

\frac{120}{( 3 - 1 ) ^{6}} = \frac{15}{2 ^{3}}

cos (3 - 1) = cos (2)

= - \frac{15}{2 ^{3}} - cos (2)

2^{3} = 8

= - \frac{15}{8} - cos (2)

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

e x p an d (x - 2 i) (x + 2 i)

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

e x p an d cot (x) + cos (x) (tan (x) - tan (\frac{x}{2}))

e x p an d (- 4 b + 2 x^{\frac{21}{5}}) (4 x^{3})
