Hello there! Are you looking for a tutor? Look no further. Friendly and understanding, I am someone who would love to help you understand different subject matter and make sure you get the grades you deserve.

A little bit about my academic background: I am currently studying Computer Science in the University of Edinburgh. Throughout my academic life I have been mainly focused on Mathematics, however, I have fair amount of experience with a lot of programming languages , alghorithms and general Computer Science subjects of matter.

Certificates related to that:
SAT II Math 2 - 800/800
Mathematics school leaving examination(Matriculation)  - 100% (I come from education system different from the UK one).

### Find minimum and maximum of x^2+1 if they exist

There are several methods of finding the extrema(plural of extremums or in other words minimum or maximum values) of a function. For now we will analyse the function using the dy/dx of f(x)=y=x2 +1, f`(x) = 2x The sign of the diferentiation of the function change at x=0. Therefore for x<0 dy/...

There are several methods of finding the extrema(plural of extremums or in other words minimum or maximum values) of a function.

For now we will analyse the function using the dy/dx of f(x)=y=x+1, f`(x) = 2x
The sign of the diferentiation of the function change at x=0. Therefore for x<0 dy/dx<0 and the function is declining. For x>0 dy/dx>0 and the function is uprising. We can conclude that there is a minimum at x=0. We cannot find a maximum of the function as it approaches infinity.

### Find the sum and product of the roots of the equation 2x^2+3x-5=0

We know that for equation ax^2+bx+c=0 a = 2,b = 3,c = -5 If the roots x1 and x2 are real numbers: x1 + x2 = -b/a = -3/2 x1*x2 = c/a = -5/2

We know that for equation ax^2+bx+c=0
a = 2,b = 3,c = -5
If the roots x1 and x2 are real numbers:
x1 + x2 = -b/a = -3/2
x1*x2 = c/a = -5/2
