Stelle um nach \(\overline{BC}\):

\(cos(\alpha)={~~\overline{AB}~~\over \overline{BC}}\)

\(\overline{BC}={~~\overline{AB}~~\over cos \alpha}\)

Berechne \(\alpha\):

\(cos(\alpha)={~~4~cm~~\over 5~cm}\)

\(\alpha=36,87°\)

In diesem Dreieck gilt:

\(1)\cos(\alpha)={a\over c}~~~2)\cos(\alpha)={b\over c}\)

\(3)\cos(\alpha)={a\over b}~~~4)\cos(\alpha)={c\over b}\)

In diesem Dreieck gilt:

\(1)\tan(\alpha)={a\over c}~~~2)\tan(\alpha)={b\over c}\)

\(3)\tan(\alpha)={a\over b}~~~4)\tan(\alpha)={b\over a}\)

In diesem Dreieck gilt:

\(1)\sin(\alpha)={a\over c}~~~2)\sin(\alpha)={b\over c}\)

\(3)\sin(\alpha)={b\over a}~~~4)\sin(\alpha)={a\over b}\)

Stelle um nach \(\overline{AB}\):

\(cos(\alpha)={~~\overline{AB}~~\over \overline{BC}}\)

\(\overline{AB}={cos(\alpha)\cdot \overline{BC}}\)
