Trigonometry flashcard 1

The tangent function is used to relate the angle of a right triangle to the ratio of the lengths of the opposite side to the adjacent side.

The hypotenuse is the side opposite the right angle and is the longest side of the triangle.

tan(X) = 32/24.

Engineers, statisticians, technicians, mathematicians, and game makers all use trigonometry.

The adjacent side is the side next to the angle that is not the hypotenuse.

Sine is the ratio of the length of the opposite side to the length of the hypotenuse.

Cosine is the ratio of the length of the adjacent side to the length of the hypotenuse.

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (a² + b² = c²).

tan(X) = 40/32.

Tangent can be expressed as the ratio of sine to cosine: tan(X) = sin(X)/cos(X).
