|---|---|---|---|---|---|
| radians | A unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.
🗑
|
||||
| coterminal angle | Two angles are coterminal if they are drawn in the standard position and both have their terminal sides in the same location.
🗑
|
||||
| quadrantal angle | An angle in standard position with terminal side lying on x-axis or y-axis
🗑
|
||||
| unit circle | a circle with a radius of one.
🗑
|
||||
| reference angle | the angle of less than 360 degrees that corresponds to an angle of over 360 degrees
🗑
|
||||
| sine | The trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
🗑
|
||||
| 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.
🗑
|
||||
| tangent | A straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.
🗑
|
||||
| cosecant | The ratio of the hypotenuse (in a right-angled triangle) to the side opposite an acute angle; the reciprocal of sine.
🗑
|
||||
| secant | The ratio of the hypotenuse to the shorter side adjacent to an acute angle (in a right-angled triangle); the reciprocal of a cosine.
🗑
|
||||
| cotangent | The length of the adjacent side divided by the length of the opposite side.
🗑
|
||||
| inverse | opposite
🗑
|
||||
| arcsin | Inverse of sine function
🗑
|
||||
| arccos | the inverse function of the cosine; the angle that has a cosine equal to a given number.
🗑
|
||||
| arctan | the inverse function of the tangent; the angle that has a tangent equal to a given number.
🗑
|
||||
| law of sines | a law stating that the ratio of a side of a plane triangle to the sine of the opposite angle is the same for all three sides.
🗑
|
||||
| law of cosines | a law stating that the square of a side of a plane triangle is equal to the sum of the squares of the other two sides minus twice the product of the other sides.
🗑
