23 lip 2024 · 💧 Calculating the hydraulic radius of a partially filled pipe is possible if you know wetted perimeter, calculated from a formula using arccos. Chemistry: 🧪 Arccos is useful for estimating the optimal bond angles of polyatomic molecules, like e.g. H 2 O \mathrm{H_2O} H 2 O or C H 4 \mathrm{CH_4} C H 4 . II Real-life examples
This function returns the arc cosine of n in radians that range between 0 and pi [0, pi]. Note: acos( ) takes argument between 1 and -1 because the mathematical value of cosine is in the range of 1 and -1.
