comment Longitude of the Ecliptic
I can't tell if you're joking, but "mods" meant "moderators", not "modulo" :)

I like the use of the second derivative in a pre-calculus problem :)

Drawing a diagram is always a good start.

Mods, consider migrating to astronomy.stackexchange.com for more attention.

comment another follow up question: modeling with exponential distributions
Am I doing the math right? Does the total time simplify to 3/(lambda1+lambda2)?

comment Outstanding balance and amount of interest
You're right, I'm wrong. I thought amortization would have an effect on annual interest, but it turns out it doesn't. You always pay the same rate of interest on the outstanding balance.

comment Outstanding balance and amount of interest
OK, to me, level annual payments means each payment must be the same amount, like in a mortgage or other amortization situation.

comment Outstanding balance and amount of interest
I might be misunderstanding your answer. What do you think each payment amount would be, if not 80?

comment Outstanding balance and amount of interest
OK, but if it's being repaid with level annual payments, then the next payment would be $80 as would all future payments, even though the balance is decreasing (unless it's an "in perpetuity" loan). We probably do need the total number of payments to work this out though.

comment How to get the distance in meters from the center of a parabolic image to a point?
It would be nice to have some distances here. What is the configuration of the soccer field (ie, how much distance between the various lines and circles we're seeing)?

This sounds like an amortization problem.

comment Motivation for Non-Euclidean geometry: relativity
A non-relativity motivation for non-Euclidean geometry is the big blue round thingy we live on.

comment Distance between a point and a 3D figure
You could write a formula for the surfaces, compute the distance from the point to each point on the surface, and minimize using calculus (+ other techniques where the surface is non-differentiable)

comment Not sure what I'm doing wrong with this recurrence problem
@OmarWali Could you add your comment to the main question by editing the question? Also, did you mean you multiplied both sides by x^2 and not x^n?
