### How do we solve this system of two trigonometric equations?

Given a system of 2 equations: $\arccos(f_1(x))=\arccos(g_1(y))$ $\sin(f_2(x))=\sin(f_3(x))$ where: Q1: $f_1(x), f_2(x), f_3(x),g_1(y)$ are linear equations over $x$ and $y$ respectively, with ...

### Finding an $\mathbb{F}_q$-point on one specific intersection of quadrics

Let $\mathbb{F}_q$ be a finite field of large characteristic and $a_1, a_2, \cdots, a_n \in \mathbb{F}_q$ be some pairwise different elements. I assume that $\sqrt{-1} \in \mathbb{F}_q$. Consider the ...

### Could distortion parameters of an image be retrieved by measuring lines only?

i have the following problem: i am given an image of an ordinary camera which is distorted meaning straight lines are not mapped into straight lines, but rather in "curvy" lines. My goal is ...

### Linearity of system of differential equations?

I am learning how to solve differential equations (ordinary and partial)and why they are so important for physics.One thing I have noticed so far is that we know so little on the nature of the ...
