Nettet31. mai 2013 · Can't you integrate sin (x)/x by using the fact that sin (x) = x - x^3/3! + x^5/5! - x^7/7! ... so sin (x)/x = 1 - x^2/3! + x^4/5! - x^6/7! ... this would give x - x^3/ (3*3!) + x^5/ (5*5!) - x^7/ (7*7!) + C, and we know that sin (x)/x -> 1 as x -> 0, so C=1. This would give us that the antiderivate of sin (x)/x is: Nettet30. mar. 2024 · Misc 7 Integrate the function sin𝑥/sin(𝑥 − 𝑎) Let I = ∫1 sin𝑥/sin ...

Nettet30. mar. 2024 · ∫sin5xdx = sin2x −sinx − 1 3 sin3x +C Explanation: We want ∫sin5xdx Rewrite the integrand as sinx(sin2x)2: ∫sinx(sin2x)2dx Recall the identity sin2x +cos2x = 1. The identity also tells us that sin2x = 1 − cos2x ∫sinx(1 − cos2x)2dx This can be solved using a simple substitution. Let u = cosx,du = − sinxdx, −du = sinxdx Rewrite the integral: NettetIntegral(sin(x^2 + 5)*x, (x, 0, 1)) Detail solution Let . Then let and substitute : The integral of a constant times a function is the constant times the integral of the function: The … NettetIntegral(sin(x)/2, (x, 0, pi/2)) Detail solution The integral of a constant times a function is the constant times the integral of the function: The integral of sine is negative cosine: So, the result is: Add the constant of integration: The answer is: load shedding schedule albertsdal
