Derivative of sinx + cosx / sinx - cosx
Web$\left(\cos x\right)\left(\sin x\right) - x\sin ^2 x + x\cos ^2 x$. My main issue is cleaning this up to get the derivative to equal $\frac{1}{2}\sin 2x + x\cos 2x$. I am not quite sure where the change from x to 2x came from. I know it's probably some old trig rules that I … Web1.

WebOver here the derivative of cosine of x looks like it is zero and negative sine of x is indeed zero. So it actually turns out that it is the case, that the derivative of cosine of x is … WebDerivatives of the Sine and Cosine Functions. We begin our exploration of the derivative for the sine function by using the formula to make a reasonable guess at its derivative. Recall that for a function f ( x), f ′ ( x) = lim h → 0 f ( x + h) − f ( x) h. Consequently, for values of h very close to 0, f ′ ( x) ≈ f ( x + h) − f ( x) h.
