What is a lambda tree. I could not find it in wikipedia.

I like linear algebra. Matrices and eigenvalues crop up everywhere in applied mathematics.

Complex analysis has that perfect balance of being both elegant and somewhat mysterious. There are a lot of fairly simple proofs of very non-obvious or very roundabout kinds of results. Analytic number theory in particular is quite mind-boggling. Euler's formula is also handy mnemonic shorthand for deriving rotations and angles/phase-shifts without having to constantly write down loads of tedious trig identities.

I find the proofs and more abstract course I took on linear algebra easier than the more computational course as easy to get sidetracked and make mistakes in the computational one with matricies.

Solving a matrix by hand is pointless in this day and age. That's what computers are for. When I say I like linear algebra I'm talking about the theory.

Everyone is different. I had to drop out of PRE calculus because I couldn't do it, and i only got through algebra by memorizing things..although i did get an A..same with trig.

Calculating with matrices does not help one to prove theorems about the linear transformations that the matrices represent.

There is more to math than calculating stuff.

The theory is the better part. Although some calculations like finding the the determinant of an upper triangular matrix with a zero on the diagonal with a zero in it. It is the product of the diagonal so entering the matrix in the computer would take longer than calculating it.

Math doesn't get interesting until you get rid of numbers.

How do you propose to do number theory, then?

He can not find number theory interesting.

Yes and no. As a mechanical calculation, not hard although integration can be a bear at times.

Done rigorously the analysis of real and complex variables requires close attention and hard work.

ruveyn

Agreed. A few weeks ago, I studied online about derivatives, and it is hella easy to do the calculations. Easier than some of the algebra stuff.

But I still haven't been able to understand and develop the intuition for slopes of curves.

Number theory is almost totally abstract, a combination of set theory and Peano's postulates. Actual numbers don't come into it until later on.

But what I meant was math doesn't become interesting until you leave calculations and arithmetic and get into the theory behind it.

I prefer to take derivitives to find where the vertex of a parabola is rather than completing the square seems easy to me. Although the intuition on slopes of curves is important and useful.
