{eq}\sin^2(45^\circ) - 2 \sin(45^\circ) \cos(45^\circ) + \cos^2(45^\circ) {/eq} Pythagorean Identity The Pythagorean identity is the identity that originated from the Pythagorean theorem. It states the addition of the sine squared ...
In trigonometry, Pythagorean identity states that the sum of sine-squared and cosine-squared of the same angle is always equal to 1: sin2(x)+cos2(x)=1. This property would be helpful in verifying whether the given equation is true or false.Answer and Explanati...
The fundamental trigonometric identity establishes that the squared sum of the sine and cosine of an angle equals 1, {eq}\sin^2 x+\cos^2 x=1 {/eq}. This identity allows us to express the cosine as a function of the sine and vice versa. In fact, by knowing the va...
