Trigonometric functions are periodic so they are many-to-one.
It is therefore important to define the domains and ranges of their inverses in such a way the the inverse function is not one-to-many. Thus the range for arcsin is [-pi/2, pi/2], arccos is [0, pi] and arctan is (-pi/2, pi/2).
However, these functions can be used, along with the periodicities to establish relations which extend solutions beyond the above ranges.

How do you work out an angle using trigonometry?
Using the Sine function Sin(x) = 0.5 Then x = Sin^(-1)0.5 x = 30 degrees. Sin^(-1) in the inverse function on you calculator. . It works for Sin , Cosine and Tangent of any angle.
What jobs use trigonometry?
there many jobs that have to uses trigonometrysuch as a carpentry , law and order these jobs have to use trigonometry because for carpentry if you don't use it then you might as well not use it any ways and you Can also use it to impress the boss you know mabye get a little raise in your money but really when you are cutting out an angle you have to use trigonometry, also architecture uses trigonometry so they can figure out how to build the complex shapes that modern buildings require
What is a use of trigonometry to find the heights of buildings and trees?
Trigonometry is the study of angles ond lengths. If you know one angle and one side length of a right traingle, you can find all the other values. If you know your distance from a tall object, and the angle made by the base of the tall object, your feet, and the top of the object, you can find the height of the object.
What grade level is trigonometry?
I was wondering if you knew but I think sophomore or junior. I was two grade levels ahead in math so I don't know for sure.
When doing trigonometry for example the cosine rule how do you know which side is a which side is b and which side is c if none of them are marked on and neither are the angles?
It's possible that either the angles or sides are labeled according to length or size.
