>>13590850For macroeconomics you'll be using linear algebra for most of your equations particularly with Z=Y=C+I+G+(X-M). Some differentiation may creep in when you're looking at productivity functions and technology
/labour relations.
For microeconomics you'll be mostly working with calculus particularly with first order differentiation. Whenever you hear the word "marginal" next to cost or rate or product etc. You will highly likely be doing first order differentiating.
For econometrics you'll be mainly working with statistics and it tends to get really technical. I would make sure you have a thorough understanding of regression analysis and stuff like OLS and maybe even Bayesian theory. Of the three, econometrics was the most technical in my experience but microeconomics can catch you off guard if you're not paying attention. Macroeconomics has a really extensive set of equations and relations, and you'll be mostly navigating between the numerous equations and expressions and it has the most memorization in my opinion.
I've only ever worked with fractional powers, some exponential stuff, basic square and square roots and I think only ONE logarithmic function when I did calculus in economics so don't sweat it too much. A basic college level text book on calculus should psyche you up. Sorry about the word salad but I hope this helps.
