comment Solve differential equation
i think you get $\sin x + \ln |\sec x|$, and must carry the absolute value unless you restrict yourself to the interval where $\cos x \ge 0$...

comment Value of Sine Function from data given
what is your approach to the problem? try to expand tangents into terms with $\sin \alpha, \sin \beta, \cos \alpha, \cos \beta$ and work it out?

@Karnivaurus some derivatives are hard to analytically express :)

comment Polynomial Interpolation and Data Integrity
When you say you evaluate $f$ at $x$, do you mean that $f:\mathbb{R} \to \mathbb{R}$ is a 1-D polynomial and $y_i=f(x_i)$ or that $f:\mathbb{R}^n \to \mathbb{R}^n$ is a vector-valued polynomial which takes $n$ inputs and returns $n$ outputs?

comment How to calculate $P(X_1 < X_2 < X_3…X_n ) $
The problem is symmetric for 2 continuous variables, so your probability there is just $1/2$.
