* The trick for a successful drawing is to eliminate slippage. So fix the centre and pin the paper to the board so it cannot slip. Find some simple drawings that you can enlarge.

Can you see how to make the scale factor variable ?

Thanks for the link.

I have contacted them about some points of English grammar.

]]>Math is a subject that is totally based on formulas there are thousands of formulas used in maths, it is not possible to remember all of those formulas you can take help from some apps like Math formulas and Physics formulas.

I'd agree with you at the high-school level, yes; most of the maths I was taught back then was more or less formulaic, and entirely context-driven. But as a subject in and of itself -- and, perhaps even as an art, some might say -- it is built up with axioms, definitions, theorems and proofs. It is certainly not totally based on formulae, and I'm glad that it isn't, because that would sap the fun right out of it for me.

]]>in WORD 2007 you can do things like this:

Type equations in linear format

You can type most equations quickly by using Math AutoCorrect codes. For example, to align an equation array, you can use @ and &, as in the following:

\eqarray(x+1&=2@1+2+3+y&=z@3/x&=6)<space>

I cannot copy here the result (it's a word graphic) so you'll have to try it yourself.

I just typed 'mathematical format' into WORD help.#

I was unable to find it online.

I found

Analytical Geometry by Pogorelov

Analytical Geometry for colleges, universities and technical schools by E. W. Nichols

neither one looks great for self teaching but you will have to remember that 99.99% of all books on math are made to be part of a course with an instructor.
