Very interesting question! A similar question is, how does the calculator figure out the value of sin, cos, etc.? Or you could ask, what did people do before the calculator was invented, i.e. before ca. ? These are all very similar questions. You can use the concept of sum and difference formulas to calculate the sine of special angles in radians. This process is different than solving equations because here you’re asked to find the trig value of a specific angle that isn’t readily marked on the unit circle Prior .

For the angle addition diagram for the sine and cosine, the line in bold with the 1 on it is of length 1. It is the hypotenuse of a right angle triangle with angle β which gives the sin β and cos cos β line is the hypotenuse of a right angle triangle with angle α so it has sides sin α and cos α both multiplied by cos is the same for the sin β line.   Other key relationships are the sum and difference formulas, which give the sine and cosine of the sum and difference of two angles in terms of sines and cosines of the angles themselves. These can be derived geometrically, using arguments which go back to Ptolemy; one can also produce them algebraically using Euler's formula.

Tables of sines and cosines for radian arguments. When calculating the sines and cosines of the angles using the SIN and COS formulas, it is necessary to use radian angle measures.

If the angle is specified in degrees, two methods can be used to translate into a radian angle measure: Download examples trigonometric SIN COS functions in Excel. circular hyperbolic functions Download circular hyperbolic functions or read online books in PDF, EPUB, Tuebl, and Mobi Format.

Because both q and r are in the same units, when q is divided by r in the preceding formula, the units cancel. Therefore, radian measure is unitless. Example 1: What is the radian measure of a central angle in a circle with radius 6 m if it subtends an arc of 24 m.

The six trigonometric functions can be defined as coordinate values of points on the Euclidean plane that are related to the unit circle, which is the circle of radius one centered at the origin O of this coordinate system.

While right-angled triangle definitions permit the definition of the trigonometric functions for angles between 0 and radian (90°), the unit circle definitions allow to.

Punch that in your calculator and you get: Then taking square roots of both sides Now we use the law of sines: We need. When you use the law of cosines to find angle B, you are making use of the three sides of the triangle. Remember the SSS congruency theorem: three sides determine the shape of a triangle uniquely.

This is why we are able to find a unique measure for angle B. When you use the law of sines, you are making use of two sides and an angle.
