He conducted an experiment using an arc lamp.

He is learning the technique of arc welding.

He told me the whole story of the incident.

An electric arc is a phenomenon where a strong current flows between electrodes.

Calculating the arctangent, which is one of the trigonometric functions, is difficult.

The calculation of arcsine is a part of trigonometry.

The calculation of the arccotangent is a part of trigonometry.

In quantum mechanics, the state of a particle is described by a wavefunction.

This program makes extensive use of built-in functions.
