Term | Definition |
Pythagorean triple | A set of three positive integers a, b, and c that satisfy the equation c2=a2+b2. |
Trigonometric ratio | A ratio of the lengths of two sides in a right triangle. |
Tangent | A trigonometric ratio, abbreviated as tan. For a right triangle ABC, the tangent of the acute angle A is tan A = length of leg opposite <A over length of leg adjacent to <A = BC over AC. |
Sine | A trigonometric ratio, abbreviated as sin. For a right triangle ABC, the sine of the acute angle A is |
Cosine | The trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse. |
Angle of elevation | When you look up at an object, the angle that your line of sight makes with a line drawn horizontally. |
Angle of depression | When you look down at an object, the angle that your line of sight makes with a line drawn horizontally |
Solve a right triangle | To find the measures of all of the sides and angles of a right triangle. |
Inverse tangent | An inverse trigonometric ratio, abbreviated as tan -1. For acute angle A, if tan A=x, then tan -1 x = m<A. |
Inverse sine | An inverse trigonometric ratio, abbreviated as sin -1. For acute angle A, if sin A=y, then sin -1 = m<A. |
Inverse cosine | An inverse trigonometric ratio, abbreviated as cos -1. For acute angle A, if cos A=z, then cos -1 = m<A. |
