Linear approximation

Показать описание

Linear approximation is about finding the equation of a line that passes very very close to the line that we're interested in, so that we can plug in the value we're interested in to get an approximate value for the function at that point. Linear approximation can be useful because sometimes you're not able to plug in exactly the value you want, because there's a problem with the function there, like a discontinuity at that point.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

I'm going to go to a higher science, but will still (number 347) & (Number 6) back with you.You've changed my recognition of math sciences, as you charge right into the thick of it and have a big enough (number 127) to carry others along.I respect and recommend you for this ability.If you need anything, never hesitate to ask.Thanks so much, Vrendus
