To calculate the area of a triangle given one side and two angles, solve for another side using the Law of Sines, then find the area with the formula: area = 1/2 × _b_ × _c_ × sin(A). Find Third Angle Determine the third angle of the triangle. For example, ...
It can help you find the length of a side of a right triangle as long as you have an angle θθ and some info on the other sides of the triangle. Example problems In this chapter, we're actually going to focus on the cosine rule. This means we'll only be working with the "Cah...
For example, let’s calculate the sine of angle α in a triangle with the length of the opposite side equal to 4 and the hypotenuse equal to 6. sin(α) =4/6 sin(α) =2/3 Sine Graph If you graph the sine function for every possible angle, it forms a repeating up/down curve. ...
Calculating an Angle in a Right Triangle The rules above allow us to do calculations with the angles, but to calculate them directly we need the inverse function. An inverse function f-1of a function f has as input and output the opposite of the function f itself. So if f(x) = y th...
For example, let’s calculate the secant of angle α in a triangle with the length of the hypotenuse equal to 8 and the adjacent side equal to 6. sec(α) = 8 / 6 = 4 / 3 Secant vs. ArccosSecant should not be confused with arccos, which is the inverse of the cosine function....
