Graphical proof and derivation of the trigonometric identity sin^2x + cos^2x = 1 using the unit circle. The proof begins by constructing a triangle inside a. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.. Visit Stack Exchang See explanation... Consider a right angled triangle with an internal angle theta: Then: sin theta = a/c cos theta = b/c So: sin^2 theta + cos^2 theta = a^2/c^2+b^2/c^2 = (a^2+b^2)/c^2 By Pythagoras a^2+b^2 = c^2, so (a^2+b^2)/c^2 = 1 So given Pythagoras, that proves the identity for theta in (0, pi/2) For angles outside that range we can use: sin (theta + pi) = -sin (theta) cos (theta + pi. The figure at the right shows a sector of a circle with radius 1. The sector is θ/(2 π) of the whole circle, so its area is θ/2.We assume here that θ < π /2. = = = = The area of triangle OAD is AB/2, or sin(θ)/2.The area of triangle OCD is CD/2, or tan(θ)/2.. Since triangle OAD lies completely inside the sector, which in turn lies completely inside triangle OCD, we hav In this lesson I will show you how to prove that sin^2x - cos^2x = 1 - 2sin^2

The Pythagorean trigonometric identity - sin^2(x) + cos^2(x) = 1 A very useful and important theorem is the pythagorean trigonometric identity. To understand and prove this theorem we can use the pythagorean theorem sin^2x = 1/2 -1/2cos2x. Rearrange the terms (multiply both sides by 2, take the constant to the sin^2(x) side, multiply both sides by -1 and you get: ==> 1 - 2sin^2(x) = cos(2x) Which is a standard trigonometry identity...

Statement: $$\sin(2x) = 2\sin(x)\cos(x)$$ Proof: The Angle Addition Formula for sine can be used: $$\sin(2x) = \sin(x + x) = \sin(x)\cos(x) + \cos(x)\sin(x) = 2\sin(x. Statement 2: $$\cos 2x = 1 - 2\sin^2 x$$ Proof 2: We can prove that $$\cos^2(x) - \sin^2(x) = 1 - 2\sin^2(x)$$ because the left-hand side is equivalent to $$\cos(2x)$$. Add $$2\sin^2(x)$$ to both sides of the equation: $$\cos^2(x) + \sin^2(x) = 1$$ This is obviously true. Statement 3: $$\cos 2x = 2\cos^2 x - 1$$ Proof: It suffices to prove that. L.H.S. = sin 2 x + 2 sin 4 x + sin 6 x= [sin 2 x + sin 6 x ] + 2 sin 4x= 2 sin 4 x cos 2 x + 2 sin 4x= 2 sin 4 x cos 2 x + 2 sin 4x= 2 sin 4 x (cos 2 x + 1)= 2

- Proving a trigonometric identity refers to showing that the identity is always true, no matter what value of x x x or θ \theta θ is used.. Because it has to hold true for all values of x x x, we cannot simply substitute in a few values of x x x to show that they are equal. It is possible that both sides are equal at several values (namely when we solve the equation), and we might falsely.
- The proof just depends on Pythagoras' Theorem: draw yourself a 90 degree triangle, label the sides o(opp), a(adj) and h(hyp) relative to angle X then sinX =o/h, cosX=a/h so sin^2X + cos^2X = 1 becomes o^2 + a^2 =h^2 which is you know who's theorem
