RE: Derivatives on HP 42S

Here's another example: \(f(x)=\sin(x+\cos(x))\) This is the power series expansion for \(f\) about the point \(x=\frac{\pi}{2}\): \(1 - \frac{1}{72} (x - \frac{\pi}{2})^6 + \frac{1}{720} (x - \frac{\pi}{2})^8 + O((x - \frac{\pi}{2})^{10})\) You should start with the initial values 1 and 2.
