. . constitutes an orthogonal system of functions on the interval sin^2(x) + cos^2(x) = 1 (the other identities are easily derived from this). So most functions with some trig function can be solved using these 2 sets of identities? This function popped up towards the end of my derivatives chapter, and the book on trig barely covered those identities at all!

Sin (2x) can be written as Sin (x+x) and substitute in equation 2 I.e. a=x and b=x and solving you get the required equation (equation 1). 20.3K views. Factoring out sin(x): sin(x)(2cos(x) - 1) = 0 Using the Zero Product property: sin(x) = 0 or 2cos(x) - 1 = 0 Solving the second equation for cos(x) we get: sin(x) = 0 or cos(x) = 1/2 So our solutions are all the angles whose sin is 0 or all the angles whose cos is 1/2. Since "x" was used for the angle instead of theta, I'm assuming we want
Trigonometriska ettan. sin 2 ( x ) + cos 2 ( x ) = 1 {\displaystyle \sin ^ {2} (x)+\cos ^ {2} (x)=1} sin ( x ) = ± 1 − cos 2 ( x ) {\displaystyle \sin (x)=\pm {\sqrt {1-\cos ^ {2} (x)}}} cos ( x ) = ± 1 − sin 2 ( x ) {\displaystyle \cos (x)=\pm {\sqrt {1-\sin ^ {2} (x)}}}
Show that f (x) = x sin (2 x) is uniformly continuous on (0, 1) https://math.stackexchange.com/q/2019987 This is a method that uses only Real Analysis: \lim_{x\to 0} x\sin x=0 and \lim_{x\to 1} x\sin x=\sin 1<\infty Since the two limits exist finitely and f is continuous on (0,1) so f is
