To find unknown sides or angles of a triangle. For triangle ABC, if C is a right angle and you are using angle A the side a is the opposite of A, side b is the adjacent side of angle A and c is the hypotenuse.
Ex: Sin A = a/c, if you know any 2 you can solve for the 3rd.
Cos A = b/c, if you know any 2 you can solve for the 3rd.
Tan A = a/b, and again, if you know any 2 you can solve for the 3rd.

The six basic functions of trigonometry are the sine, cosine, tangent, cosecant, secant, and cotangent functions. Abbreviated sin, cos, tan, csc, sec, cot.
Trigonometry functions are used to work out the various properties of triangles.
In geometry, similar shapes have the same angles. This means that the values of the basic trigonometric functions of these angles are the same.
The 3 most common trigonometry functions are as follows:Sine (opposite/ hypotenuse)Cosine (adjacent/hypotenuse)Tangent (opposite/adjacent)An easier way to remember these is SOH-CAH-TOA which, when pronounced out-loud, sounds kind of like "soak a toe".
Trigonometry is used in many jobs! Trigonometry is used in forestry(to calculate height of trees), A variety of Engineering jobs, Coast Guards and Flight Coordinators use Trigonometry with vector math to deal with movement through water/air currents. Carpenters need to know basic trigonometry. Any job dealing with any type of waves(sound waves, the pattern that the tide follows) has to know about Trigonometric Functions. I could keep listing jobs but the basics are: 1) any job that involves practical design(meaning not fashion design) 2) any job that requires basic physics or calculus 3) any job that requires basic high school math Trigonometry shows up everywhere, in order to be good with numbers, you have to be good with trigonometry
