tan (x) = \frac{8}{13}

Allgemeine Lösung für

tan (x) = \frac{8}{13}

tan (x) = a \Rightarrow x = arctan (a) + πn

x = arctan (\frac{8}{13}) + πn

x = arctan (\frac{8}{13}) + πn

arccos (x) = \frac{5}{6}

5 cos (x) = - 2 sin^{2} (x) + 4, 0 \leq x \leq 2 π

4^{\frac{1}{3}} sec (x) = 4 (\frac{1}{4 ^{\frac{1}{3}}}) csc (x)

\frac{1 + tan ^{2} ( x )}{1 + tan ^{2} ( x )} = 1 - sin^{2} (x)
