Calcea Johnson and Ne'Kiya Jackson believe they can prove the Pythagorean Theorem using trigonometry ... of the Pythagorean trig identity \sin^2x + \cos^2x = 1." RELATED VIDEO: Professor's ...
This is because trigonometric functions such as sine and cosine are built on relationships derived from right-angled triangles. Using these functions to prove a theorem that justifies their own ...
A mathematical theorem stating that a PERIODIC function f(x) which is reasonably continuous may be expressed as the sum of a series of sine or cosine terms (called the Fourier series), each of which ...
Why? Because trigonometry itself is built upon the very theorem it seeks to prove. Any attempt at using sine, cosine, or ...
