Step 1
Integration of a function gives the result as the area covered by the function with an appropriate axis. INtegrals are of two types, definite and indefinite integrals.
Definite integrals are defined for a limit of variable from a lower limit to an upper limit. This is represented by the expression:-
Here, F(x) is the anti-derivative of the function f(x).
Step 2
The value of the definite integral is constructed by using the limits of x from -2 to 2, and the limts of y from 3 to 4 as I=3422f(x,y)dxdy. This integral is calculated as follows:-

Can anyone help with paramaterization of conics?
Im struggling to wrap my head around an example. It considers the conic x2+y2z2=0 then proceeds:
Take A=[1,0,1] and the line P(U) defined by x=0. Note that this conic and the point and line are defined over any field since the coefficients are 0 or 1. A point XP(U) is of the form X=[0,1,t] or [0, 0, 1] and the map α is

α ( [ 0 , 1 , t ] ) = [ B ( ( 0 , 1 , t ) , ( 0 , 1 , t ) ) ( 1 , 0 , 1 ) 2 B ( ( 1 , 0 , 1 ) , ( 0 , 1 , t ) ) ( 0 , 1 , t ) ] = [ 1 t 2 , 2 t , 1 + t 2 ]  or  α ( [ 0 , 0 , 1 ] ) = [ 1 , 0 , 1 ] .

How do I evaluate B(v,v) or B(v,v)(a,b,c) like they have to go from the first line to the second?

Intermediate value theorem on infinite interval R
I have a continious function f that is strictly increasing. And a continious function g that is strictly decreasing. How to I rigorously prove that f ( x ) = g ( x ) has a unique solution?
Intuitively, I understand that if I take limits to infinity, then f grows really large and g grows very small so the difference is less than zero. If I take the limits to negative infinity then the opposite happens. Using the intermediate value theorem, there must be an intersection, and since they are strictly increasing/decreasing, only one intersection happens.
My question is how do I apply the intermediate value theorem here? I don't have the interval to apply it on. I don't know when f crosses g and therefore can't take any interval. Or is there some sort of axiom applied here that I am missing?
