Objective. Students will practice applying the law of cosines to calculate the side length of a triangle and to calculate the measure of an angle. Students will also extend their thinking by applying the law of cosines to word problems and challenge questions.There are many other tools useful when dealing with trigonometry problems. Check out two popular trigonometric laws: law of sines and law of cosines calculators, helping to solve any kind of a triangle. If you want to read more about the trigonometric functions, go to our dedicated tools: sine ; cosine; tangent

In a right triangle with legs a and b and hypotenuse c, and angle α opposite side a, the trigonometric functions sine and cosine are defined as sinα = a/c, cosα = b/c. This definition only covers the case of acute positive angles α: 0<α<90°.

law_of_sines-cosines_area_of_triangle-key.jnt: File Size: 180 kb: File Type: jnt A better wording is “Sine is your height, as a percentage of the hypotenuse”. (Sine becomes negative if your angle points “underground”. Cosine becomes negative when your angle points backwards.) Let’s simplify the calculation by assuming we’re on the unit circle (radius 1). Now we can skip the division by 1 and just say sine = height. Algebra 2 Lecture Notes. Quick Links to Chapter Lecture Notes.
