So I need to brush up on my basic trignometry (and maybe some geometry)...

....it's been YEARS (years!) since I've cracked a book on anything even remotely related to geometry or trig, and I'll be the first to admit, I remember NON of it... Not one iota.

But I'm going to start taking some Autocad classes for work (allows me to cross train on other functions in my department, more job security, more money, etc....). I asked our Engineer if there's anything I should read or brush up on in the meantime, and he said, "You've taken trig and geometry, right?" I said, "yeah, like trig 101, one semester, many many years ago...." He shrugged and didn't seem concerned, but ... well... I am!!

So does anyone have any recommendation as to a good book (is there a "trig for dummies" :lol: ) or books to get me reacqainted?

:lol: Library? Is that one of those buildings with all the books? I don't think I've been in one of those since the advent of the internet! :lol:

(j/k... I actually am a proud library card holder ;) )

I was thinking I might just hit the college book store. Just didn't know if anyone had any other brilliant ideas.

*sigh*

Studying. :lol:

If you dont' remember any of it, a college bookstore might be a little hard to digest. Check the local yellow pages under "teacher aids" or Home schooling supplies. Find the high school geometry and trig books. YOu should be able to get the teacher's key and the work book.

For mechanical cad work yes i would recommened it.
there is a ton of trig geometry and even calculus in surveying but glad im just a draftsman so i dont have to rack my brain but i gonna start learning it eventually :p

From my days in school, I worked with both PRO-E and AutoCAD (I was going into engineering) and I learned more from just playing with the program and seeing what it could/couldn't do than anything. I took CAD before I took trig, and PRO-E at the same time as trig, I didn't think they had much in common, but that's me. :2cents:

Ahhh, another drafter..... seen the movie "Falling Down"? Watch that first :lol: . After that it depends on your company. I have worked for some places where all you need to do is shut your brain off, and click buttons. The place I am at now, pretty much has me do engineering work without the pay of an engineer. So depending on what kind of work they give you will determine whether or not you need to know any math.

Side note: even though Autocad has an autosave function, forget it exists and constantly save. Computers crash, and that will cause you to get violent. :lol:

:lol:

I'm wanting to milk this Autocad training and whatever cross training they'll give me here what everything it's worth... I wanna learn whatever I can, so if it'll be advantageous long-term for me to have a better understanding of the mathematical side of things, then I'm all for it.

Ah, and thanks for the reminder about autosave/crashing... :lol:
