By SohCahToa, the S, C, and T stand for the trigonometric functions, sine, cosine, and tangent. The three parts can be broken down as follows:
The values of the trigonometric functions can be found when two sides of a right triangle are given. The third side can be found using the Pythagorean Theorem.
For a right triangle with a hypotenuse of length h and legs of length a and o:
a2 + o2 = h2
Find sin(θ), cos(θ), and tan(θ) for the right triangle below.
First, find the hypotenuse, h, using the Pythagorean Theorem, where a = 6 and o = 10.
Find the hypotenuse and adjacent side for the right triangle below.
We'll find h first.
h = 8
We'll use tangent to find a next.
You could also use the cosine function to find a since you have the value for c. You could even use the Pythagorean Theorem to find a since you know the other two sides of the triangle.
