Negative angles Consider the unit circle showing angles 6 and —9. cos 9 = x cos (—6) = x Thus, sin = Y sin (—6) = —Y tan = tan(—6) = cos(—9) = cos e = —sm Method for finding the trigonometric ratio for any angle between 00 and 3600. 1.
(Things are definitely moving here in trig land.) Look carefully, and you'll see that perpendicular lines have been added to form a few right triangles. First off, notice that ∠BOE = α + β. This means that sin(∠BOE) = sin(α + β). Now, look at ΔOAE and bust out our trig ratio for the sine. Since BD = AC, we can rewrite that as .

Each table has two boxes. The box on top is the numerator and the box at the bottom is the denominator. Therefore, each table represents a ratio. Enter a ratio with two values in either table. Then enter only one value in the other table either on the box on top or the box at the bottom depending on the problem you are solving.

Introduction: In this lesson, three trigonometric ratios (sine, cosine, and tangent) will be defined and applied. These involve ratios of the lengths of the sides in a right triangle. In a right triangle, one angle is 90º and the side across from this angle is called the hypotenuse.
Using the "special" triangles above, we can find the exact trigonometric ratios for angles of pi/3, pi/4 and pi/6. These triangles can be constructed quite easily and provide a simple way of remembering the trigonometric ratios. The table below lists some of the more common angles (in both radians and degrees) and their exact trigonometric ratios.

(b) What is the ratio of the number of blue pencils to the total number of pencils? So, for every circle, 2 π radii subtend a "central angle" of 360° and therefore one radius would subtend a central angle of 360° ÷ (2 • π) = 180° ÷ π = 57.295779513... degrees = 1 radian . Some of the more common angles expressed in radians are: 180° = π radians 90° = π ÷ 2 radians 60° = π ÷ 3 radians

Everything in trigonometry seems to revolve around the 90 degree triangle and its ratios. A 90 degree triangle is defined as a triangle with a right angle or in other words a ninety degree angle. Given any known side length of a 90 degree triangle and one other value (another side, angle, area value, etc), one can find all unknown values of the ...
General Trig Notes. We generally work in radians rather than degrees. The 360 degrees in a circle are equivalent to 2Π radians; thus, one radian is 360/(2Π), or about 57.3 degrees. This may seem a bit odd till you think of the circle's circumference, which is 2Πr; if r (the circle's radius) is one, the circumference is indeed 2 Π.
Oct 17, 2012 · for angle x between 270 and 360, sine (x) = minus sine (360 - x) and for angle x between 180 and 270, tangent (x) = plus tangent (270 - x) should have been for angle x between 180 and 270, tangent (x) = plus tangent (x - 180) Again, it is best to look in a text book, e.g., see 'Algebra and Trigonometry' (Second edition) by Stanley I. Grossman

The second table had more information covered up. After a discussion the groups decided there wasn’t enough information and they would have to guess what the missing numbers were. Estimated messy mean C (pdf) The third table had minimal information. Each group used their own method to find the missing values.
The value of a trigonometric function of an angle over 90 degrees (or less than zero degrees) is not always the same as the value of its reference angle, but they can be easily evaluated. Since any trigonometric function can be written in terms of the sine and cosine functions I am going to deal wit these functions only.
We do that by dividing the angle measure in degrees by 360°. For example, to draw a 90° angle, we calculate that 90° 360° = 1 4. 90° 360° = 1 4. So, the terminal side will be one-fourth of the way around the circle, moving counterclockwise from the positive x-axis. To draw a 360° angle, we calculate that 360° 360° = 1. 360° 360° = 1.

Values of Trigonometric Ratios for Standard Angles Trigonometric Functions in Right Triangles Sine: The sine of an angle is the trigonometric ratio of the opposite side to the hypotenuse of a right triangle containing that angle.
Trigonometric ratios can also be represented using the unit circle, which is the circle of radius 1 centered at the origin in the plane. In this setting, the terminal side of an angle A placed in standard position will intersect the unit circle in a point (x,y), where = ⁡ and = ⁡.
