Web4. Both answers are correct. Note that t + 180 ∘ and t − 180 ∘ differ by 360 ∘, so they have the same cosine (and sine). Let's verify that cos ( t + 180 ∘) = − cos t.

Removing the parameter in parametric equations (example 2) - Khan Academy
Webx = 3 cos (-t), y = 2 sin (-t) And now as time moves forward, the object rotates clockwise (negative angle). This example can be a bit confusing because the parameter could be angle. But I think that's a bad assumption. If that's what we meant, we should write "theta" or some other greek letter to make that clear. Webgocphim.net WebJun 12, 2015 · Applying this theorem, An Extended Frullani Integral, where f(x) = cos(x), F(x) = ∫x0f(t)dt, and ˉF(x) = 1 xF(x), we find that F ′ (0) = 1 and limx → ∞ˉF(x) = 0. We find immediately that ∫∞ 0 cos(6t) − cos(4t) t dt = log(2 / 3) And we are done!! From Frullani's Theorem we have ∫∞ 0 f(ax) − f(bx) x dx = (f(0) − f(∞))log(b / a) Here, we can write otto deutsch razor
