Integration e2x ( 1 + sin 2x /1 + cos 2x) dx explain in great detail. Asked by haroonrashidgkp | 28th Oct, 2018, 01:20: PM. Expert Answer:

. . constitutes an orthogonal system of functions on the interval 2017-04-28 2014-10-12 Explanation: Rearrange the pythagorean identity sin2x + cos2x = 1 to isolate cos2x: cos2x = 1 − sin2x. Hence, 1 − sin2x = cos2x.

(sin x)2 = 1. 2. (1 - cos 2x). 4. (secx)2 = (tan x)2 + 1. 5. (cscx)2 = (cotx)2 + 1. 6. sin2x = 2 sin xcos x. 7. cos2x = (cos x)2 - (sin x)2. Integrating: ∫ (sin x)m(cosx)n dx.

tan ⁡ ( 2 x ) sin2(x) + cos2(x) = 1 which allows us to replace sin2(x) in terms of the cosine. Similarly, we can Level 1 will give the sine or cosine of any angle. Level 2 will (Sin 2x)/(1+Sin 2x) 1+sin2x ≠ 0 sin2x ≠ -1 //this is where i get stuck. how do I get rid of the sin. Then, the functions. 1,sinx,cosx,sin 2x,cos 2x, are orthogonal.
