How do I write a exponential function in the form P(t)=P(a)^t with the two points (1,12) and (2,48). Do I take the ratio and use that for a or do I use 12 as the initial values and substitute in a x and y to find a?

What is the best one? All the ones I am finding are making me pay to see the steps involved. I'm fine with that, but I want a good one that doesn't give non-standard steps. Sometimes I can figure out the steps based on the solution given, which is actually helpful in learning.

How much math do I need in order to self-study undergrad level Economics and Finance?
Recently got some great Textbook Recommendations
I'm all in

What are the things that make us say math is not perfect? What are the problems and inconsinstencies that make it imperfect?

I'm starting a degree in aerospace engineering in september. But I'm fucked. Even though I was good at math, I skipped large parts of it during high school and now have massive gaps in my knowledge.

Can you guys recommend a good undergraduate textbook to fill in the gaps that's clear and coherent?

I've noticed something: mathematicians are skinny.

Also: chess grandmasters are skinny.

Discuss!

are there any online resources you recommend on where to take on some math excerise like equation and expression (with solutions of course)? i want to avoid to buy or resurrect my old math textbook and want to fix this huge breach in my knowledge.
