## Greeatings!

Not much to introduce. A middle-aged lad trying to re-learn what he has forgotten during last 20 or so years, meaning everything beyond basic arithmetic. Shy as one can be and embarrassed about how weak my memory is, I'm just going to leave it at that.

## Re: Greeatings!

Thank you for taking interest. I guess I should've mentioned in my introduction what I'm working with. Any ideas and suggestions about what follows are greatly appreciated.

Yes, I'm working through a series of texts:

Algebra: Israel M. Gelfand, Alexander Shen (this one I've more or less gone through, though I couldn't answer all the exercises in all sections)

Functions and Graphs: M. Gelfand, E.G. Glagoleva, E.E. Shnol (this one I've more or less gone through, though I couldn't answer all the exercises in all sections)

Method of Coordinates: A. S. Smogorzhevky (going through it at the moment to make sure I'm ready for next ones)

Trigonometry: M. Gelfand, M. Saul (to be worked with in future)

Kiselev's Geometry, Book I. Planimetry and Book II. Stereometry (to be worked with in future)

The reason why I chose these books in particular is because they claim to be written for a student working without a teacher (and being written decades ago, they don't assume fancy mathematical programs or a graphing calculator). The books seem to encourage readers to work out some simple proofs for things as well and proofs are something with which I've worked very little, if at all really.

I try to work without a calculator as much as possible for, ahem, reasons. To double check my thoughts I use FooPlot | Online graphing calculator and function plotter for graphs and check most of my answers with GNU bc when problems involve trigonometric functions or other things I can't do in my head.

During last autumn I took one MOOC pre-calculus class from which managed to pry out 76% grade, after some tears. From this I infer I'm not even close to being ready for calculus. Especially trigonometry proved to be something I've forgotten completely, however I'm not sure if I ever even learned it in the first place.

My plan is to proceed to calculus after I've worked my way through books listed above, probably with Mooculus as it seems to be targeted for people with no previous exposure to calculus.
