Why is [math]\int \sin x \cos x dx = \frac{1}{2} sin^2 x + C[/math] and not [math]-\cos x + C[/math]?
What is integral of [math] \int e^x \frac{1-\sin x}{1-\cos x} ~dx [/math]?
מדוע [math]\int \sin x \cos x dx = \frac{1}{2} sin^2 x + C[/math] ולא [math]-\cos x + C[/math]?
מהו אינטגרל של [מתמטיקה] \int e^x \frac{1-\sin x}{1-\cos x} ~dx [/math]?
