vereinfachen 1/2 (-1/7 cos(7x)-1/5 cos(5x))

Lösung

vereinfachen

\frac{1}{2} (- \frac{1}{7} cos (7 x) - \frac{1}{5} cos (5 x))

\frac{- \frac{1}{7} cos ( 7 x ) - \frac{1}{5} cos ( 5 x )}{2}

Schritte zur Lösung

\frac{1}{2} (- \frac{1}{7} cos (7 x) - \frac{1}{5} cos (5 x))

Wende Bruchregel an:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot ( - \frac{1}{7} cos ( 7 x ) - \frac{1}{5} cos ( 5 x ) )}{2}

Apply rule:

1 \cdot a = a

1 \cdot (- \frac{1}{7} cos (7 x) - \frac{1}{5} cos (5 x)) = (- \frac{1}{7} cos (7 x) - \frac{1}{5} cos (5 x))

= \frac{- \frac{1}{7} cos ( 7 x ) - \frac{1}{5} cos ( 5 x )}{2}
