WebSep 2, 2024 · This second part gives you what you want. x ↦ sin ( x) x is smooth, even analytic, and so its antiderivative exists, and is equal to some integral of the above type. FWIW, a specific antiderivative (namely the one which attains value 0 at x = 0) for this particular function has a name, it is called the sine integral, denoted S i ( x) and taken as WebDetermine the derivative. f(x) = sin(1/x) f'(x) = (-1/x 2)cos(1/x). Find critical values. 0 = (-1/x 2)cos(1/x). 0 = cos(1/x) π/2 = 1/x. 2/π = x. Use test points. f ... church office online cost

WebSo, here in this case, when our sine function is sin(x+Pi/2), comparing it with the original sinusoidal function, we get C=(-Pi/2). Hence we will be doing a phase shift in the left. So is the case with sin(x-Pi/2), in which we get C as Pi/2, hence the graph shifts … WebSo the derivative, f ′ ( t), has to be the tangent vector on the circle in the counter-clockwise direction. It is thus perpendicular to f ( t) and has to have length 1. This shows that f ′ ( t) = ( − sin t, cos t). In particular, then, the derivative of sin t is cos t. So sin ( x + h) − sin x = sin x ( cos h − 1) + cos x sin h ... WebEnter your queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary.
