if I have a relation between $A\times A$

if $A=\{1,2,3\}$

if $B=\{1,2,3\}$

$R=\{(1,1),(2,2),(3,3)\}$

can I say that the Relation R is Reflexive and also a Symmetric because I have (a,b) and (b,a) and also (a,a).

$\frac{dy}{dx}}=f(x,y)$

where $f(x,y)$ is a homogeneous function. I found some examples like $f(x,y)=(x+y{)}^{2}$ where it can be solved after converting it to Ricatti's equation.

thanks

The transformation ${R}^{2}->{R}^{2}$ is represented by the matrix $\left(\begin{array}{cc}1& 2\\ 1& 0\end{array}\right)$.

$\frac{dy}{dx}=\frac{x-\mathrm{exp}(y)}{y+\mathrm{exp}(y)}$

I thought I could use separation of variable, but I'm unable to isolate x.

Could you please help me get started on this differential equation?

A = {{1, -1}, {2, -2}, {3, -3}};

Find the image of {1,3} under A and determine if {3,6,9} is in the range of the transformation.

Given the plane equation $ax+by+cz=d$ and an arbitrary point in 3D space $(i,j,k)$, how do I find a homogenous transformation matrix that is used to reflect this point about the plane?

College Math problems only seem challenging at first, yet what they truly represent is not much harder than high school Math with some equations that are closer to the engineering approach. Approaching your college math helper is essential because your questions may just have to be worded differently. Regardless if you are dealing with equations or need answers to your college math questions, taking a look at college math equations will let you see things differently. Approach college math answers step-by-step. The majority of college math problems with answers represented here will be similar to what you already have.
