I graduated my undergrad with a BS in mathematics but I have lost my interest since then. The link sparked something in me for about a second and then I said "what the hell am I thinking?"

I'd be interested in seeing exactly what he did. I have a few ideas, but I'll keep them to myself to continue to hide my geekiness

I'm curious to see what his system entails but a little sceptical too. He says it lets you solve trig problems with algebra. Well, duh, trig values can be derived from ratios and that's simple algebra. There has to be more to it than just relabeling the concepts though ...

I'm almost wondering if he's using matrix algebra to redefine coordinate planes so that angles are always orthogonal. It's a fairly simple transform, but still more work then just using normal trig

Without seeing it, I would guess that's exactly what it is.

Being an engineering student, I am concerned with how uniqueness and linearity might be comprimised... However, this is all speculation since I haven't read the book.

Graduated in 1975.  Yes, I'm ancient (52).  When I started in '71, it was during the transition from slide rules to electronic pocket calculators...

that's about when my dad graduated. Believe me, I've heard all about slide rules and the like. He still has his old HP calculator. Not exactly a pocket calculator tho. It has a diode lit screen and needs to plug into a wall outlet. He used it up until 4 years ago when we bought him a more modern version. We still catch him using the slide rule occasionally tho

I have a finance degree. I know I know it is different...

I have a slide rule framed hanging on my wall as a reminder of the past...

I left a math and science track to study art instead.  Never got very far in my math studies, but I always loved it.

Is there a way I could please be an honorary math geek?  Please?  I really do want to get back to studying math again at some point.  Pretty please?

I'd like to know more about it, also.. I don't have a solid hold on trig yet, as I realized going through my Calc class this semester

That is kind of scary. I see no why it is beifitial beyond simple geometric problems. He even says it makes the radius relation non-linear. Basicly you can accomplish the same stuff with parametric equations.

Anyone with a math program on their computer is considered a geek in my books



I have never used a slide rule, though I have seen archaic calculators - reverse polish notation calculators. However, the stack size of my brain wasn't large enough to really use it. We have engineering classes where calculators aren't permitted, and I wrote a semiconductor physics exam where a calculator just wasn't needed.

hey, RPN isn't archaic....

I LOVE RPN. RPN + stack notation is the best thing since sliced bread

During my undergrad we weren't permitted to use calculators for all exams in calculus courses and most exams in other math courses.

All ratios were done with the 45,45,90 or 30,60,90 triangles if any sine, cos, tan calculations were necessary.

Hasn't anyone thought that maybe people actually LIKE trig the way it is? I love it...as I use it EVERY DAY. I'd be lost without my trig functions, I'd be out of a job if I tried to tell the people here that I needed them to rethink the way we do our geometry and solve our angle problems in other ways. OUCH!! LOL

Interesting approach though, but I agree with a previous post...trig is solved in substitution and ratios anyway, which really IS just simple algebra. Hmmph...but then again, I'm a REAL math geek...

I have calculus tattooed on my right calf, and I still have my quadratic equation t-shirt from high school.
