WebbThe values of trigonometric numbers can be derived through a combination of methods. The values of sine and cosine of 30, 45, and 60 degrees are derived by analysis of the 30-60-90 and 90-45-45 triangles. If the angle is expressed in radians as , this takes care of the case where a is 1 and b is 2, 3, 4, or 6. The trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values. These values are listed in the following table for angles from 0° to 90°. For angles outside of this range, trigonometric values can be found by applying the reflection and shift identities. In the table below, stands for the ratio 1:0. These values can also be considered to be undefined (see division by zero).
WebbThe number π (/paɪ/; spelled out as "pi") is a mathematical constant that is the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. The number π … WebbAccurate trigonometric ratios for 0°, 30°, 45°, 60° and 90° The trigonometric ratios for the angles 30°, 45° and 60° can be calculated using two special triangles.
WebbAs the other answer says, you simply can't express all values of trigonometric functions as fractions. I am guessing that on your TI-84, if you set the calculator to give you the fractions, then sin ( 30 ∘) = sin ( π / 6) will give you 1 2 (that is how it works on my TI-84). But you also know that, for example, sin ( 45 ∘) = sin ( π / 4 ... WebbThe Sine function ( sin (x) ) The sine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the opposite …
Webb1 dec. 2015 · The cosine is easier: co sine = co mplement's sine, so cosθ = sin(90 ∘ − θ). The point is that you can just read off the trig functions of 45 ∘ from the 45 ∘ - 45 ∘ - 90 ∘ triangle: sin45 ∘ = 1 / √2, cos45 ∘ = sin(90 ∘ − 45 ∘) = sin45 ∘ = 1 / √2, and tan45 ∘ = sin45 ∘ / cos45 ∘ = (1 / √2) / (1 / √2) = 1.
