erweitern x(20.4+k(x)=k(x)*cosh((72-x)/(k(x))))

Lösung

erweitern

x (20.4 + k (x) = k (x) \cdot cosh (\frac{72 - x}{k ( x )}))

20.4 x + x k (x) = cosh (\frac{72 - x}{k ( x )}) k (x)

Schritte zur Lösung

x (20.4 + k (x) = k (x) cosh (\frac{72 - x}{k ( x )}))

= x (20.4 + = cosh (\frac{72 - x}{k ( x )}) k (x) k (x))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = x, b = 20.4, c = k (x) = k (x) cosh (\frac{72 - x}{k ( x )})

x \cdot 20.4 + x k (x) = k (x) cosh (\frac{72 - x}{k ( x )})

20.4 x + x k (x) = cosh (\frac{72 - x}{k ( x )}) k (x)
