If, by trigonometry theorem you mean the "fundamental theorem of trigonometry," sin2(x) + cos2(x) = 1, it is actually the Pythagorean Theorem. if you have a right triangle with a hypotenuse of one, sin(x) is one leg, and cos(x) is the other. The Pythagorean Theorem states that a2 + b2 = c2 and therefore sin2(x) + cos2(x) = 1.

What does the formula for Pythagoras Theorem mean?
It means there is a fixed relationship between the three sides of a right angled triangle. If you know the length of two of the sides then the third can be calculated. It has other implications in geometry and trigonometry also.
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
