QUESTION: Dear Prof Scott

As per the attached image, Will you consider this Coordinate Geometry

Variation as correct or incorrect ?.

The Four Quadrants Positions are changed along with the positive and negative numbers on the x and y axis.

Awaiting your reply,

Thanks & Regards,

Prashant S Akerkar

ANSWER: Yes, that looks correct, for it just the normal coordinate system rotated by 180.

QUESTION: Dear Prof Scott

Thanks.

The equations, curves plotted using

these coordinate geometry variation would

be interesting?.

Thanks & Regards,

Prashant s Akerkar

From what I can tell, it looks like with that variation on plotting the curve would be to rotate it by 180 degrees. I'm not sure if that's really of any interest since the piece of paper they're plotted on just needs to be turned over. Doing so would make both look the same.

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later.
I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman.
I tutored at Mathnasium for well over a year.
I worked at The Boeing Company for over 5 years.
I received an MS degreee in Mathematics from Oregon State Univeristy.
The classes I took were over 100 hours of upper division credits in mathematical courses such as
calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more.
I graduated with honors in both my BS and MS degrees.
Past/Present Clients: College Students at Oregon State University, various math people since college,
over 7,500 people on the PC from the US and rest the world.
**Publications**

My master's paper was published in the OSU journal.
The subject of it was Numerical Analysis used in shock waves and rarefaction fans.
It dealt with discontinuities that arose over time.
They were solved using the Leap Frog method.
That method was used and improvements of it were shown.
The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.
**Education/Credentials**

Master of Science at OSU with high honors in mathematics.
Bachelor of Science at OSU with high honors in mathematical sciences.
This degree involved mathematics, statistics, and computer science.
I also took sophmore level physics and chemistry while I was attending college.
On the side I took raquetball, but that's still not relevant.
**Awards and Honors**

I earned high honors in both my BS degree and MS degree from Oregon State.
I was in near the top in most of my classes. In several classes in mathematics, I was first.
In a class of over 100 students, I was always one of the first ones to complete the test.
I graduated with well over 50 credits in upper division mathematics.
**Past/Present Clients**

My clients have been students at OSU, people who live nearby, friends with math questions,
and several people every day on the PC. I would guess that you are probably going to be one more.
