I'm trying to work out whether a point is on or below the line segment defined by those two point.

Currently I'm using $Ax+By+C=0$ to see if a point is on or below this line segment and this works correctly except for when the point is of the form $(0,y)$ or $(x,0)$

What am I doing wrong? Do I need to use a different form of the linear equation?

${a}_{k}=\frac{1}{2}p({a}_{k+1}+1)+\frac{1}{2}p({a}_{k-1}+1)+(1-p)({a}_{k}+1)\iff p{a}_{k}=1+\frac{1}{2}p{a}_{k-1}+\frac{1}{2}p{a}_{k+1}$. Thus if we let ${b}_{k}=p{a}_{k},$, then it is equivalent to ${b}_{k}=1+\frac{1}{2}{b}_{k-1}+\frac{1}{2}{b}_{k+1}$, which has solution as above. But how to solve this one about ${b}_{k}$?

$\frac{\mathrm{d}C}{\mathrm{d}t}=AC+C{A}^{\mathrm{T}}$

where $C$ is a symmetric $n\times n$ matrix and $A$ is a $n\times n$ matrix. Find $C(t)$.

Is there a formal solution for the above equation? This is in principle linear equation if we treat the matrix $C$ and $A$ as a ${n}^{2}$ vector. However, it does not seem to be practical way to solve the problem.

This kind of differential equations for matrices is quite new to me. Besides the formal solution let me know some books considering similar topic.

The impulse response of a system is the output from this system when excited by an input signal $\delta (k)$ that is zero everywhere, except at $k=0$, where it is equal to 1. Using this definition and the general form of the solution of a difference equation, write the output of a linear system described by:

$y(k)\u20133y(k\u20131)\u20134y(k\u20132)=\delta (k)+2\delta (k\u20131)$

The initial conditions are: $y(\u20132)=y(\u20131)=0$.

My question is: How can the particular solution be found using the method of undetermined coefficients if the non-homogeneous equation is also a difference equation?

Students dealing with post-secondary Algebra will know that linear equation standard form examples are quite hard to find, let alone obtain solutions to questions related to algebraic problems. Luckily, you will find suitable answers to your linear equation standard form tasks by turning to help based on provided solutions. Even though one may use several calculators online, the college professors will require a verbal or written explanation, which is where provided forms of linear equations answers always help to avoid trouble and see the reasoning.
