B t sin 2t cos 2t derivative
WebThe derivative turns out to be $-10\sin\left(2t+\frac{\pi}{4}\right)$. You wanted to find out where this is $0$, and used the formula for the sine of a sum. It is much easier to note that the derivative is $0$ when $2t+\frac{\pi}{4}$ is a multiple of $\pi$. But examining the derivative to find the maximum is not the best procedure here. WebThe derivative of x with respect to t is just going to be equal to, let's see, the derivative of the outside, with respect to the inside, it's going to be two sine whoops, the derivative of sign is cosine, two cosine of one plus three t, times the derivative of the inside with respect to t. So that's going to be, derivative of one is just zero.

WebThe derivative of sin of T is cosine of T, cosine of T. So, our arc length up here is going to be equal to the integral from T is equal to zero to pi over two, that's what we care about, our parameter's going from zero to pi over two of the square root of the derivative of X with respect to T squared. That's a negative sin of T squared, well ... WebSep 7, 2024 · Figure \(\PageIndex{2}\): These graphs show two important limits needed to establish the derivative formulas for the sine and cosine functions. We also recall the following trigonometric identity for the sine of the sum of two angles: \[\sin (x+h)=\sin x\cos h+\cos x\sin h. \nonumber \]
