## Notation and denominations

The sides in a right-angled triangle have the name of where they stand in relation to the right angle and the angle that is being examined. The longest side is called hypotenus and is the only page that is not right on one of the other sides. The other sides are called catheters, and they stand straight on each other. The catheter that is torn between the angular bone to the current angle is called the opposite catheter. The catheter that forms an angle of bone is called the adjacent catheter.

The denomination of the conditions in the triangle is shortened. Sinus becomes its cosine becomes cos, and the tongs become tan. The angle for which is written is based on the relationship, for example cos v, or tan 38.

When the ratio is set to power, it is written with the value of the increase to the ratio before the angle, for example, sin2 v. If it is written after the angle, it is perceived that the angle is in power, for example sin v2.
