WebbCos2x. Cos2x is one of the important trigonometric identities used in trigonometry to find the value of the cosine trigonometric function for double angles. It is also called a double angle identity of the cosine function. The identity of cos2x helps in representing the cosine of a compound angle 2x in terms of sine and cosine trigonometric functions, in terms of … Webb13 feb. 2024 · 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 …
