tan(2x) = 2 tan(x) / (1. Primitiv funktion till sin2x. Vi introducerar begreppet primitiv funktion och undersöker sambandet mellan denna primitiva funktion och dess derivata. After doing so, the first of these formulae becomes: sin (x + x) = sin x cos x + cos x sin x so that sin2x = 2 sin x cos x.

2) du. = 1. 5 u5. -.

cos(2x) = cos 2 (x) - sin 2 (x) = 2 cos 2 (x) - 1 = 1 - 2 sin 2 (x).

Learn sine double angle formula to expand functions like sin(2x), sin(2A) and so on with proofs and problems to learn use of sin(2θ) identity in trigonometry.

Ao=1/2pi ∫sin2x dx (from -pi to 0) When I do the integral, I get cos2x and cos0-cos2pi=0. For Bn; Bn=1/pi ∫sin2x sinnx dx (from -pi to 0) When I do the integral, again I get 0. So, the only coefficient i have is An. So, the fourier series of fx becomes fx~ƩAn cosnx which seems incorrect. I checked my algebra maybe 10 times but there is no
