hi good friends!
I searched the web for a document that contain history of logarithm but didn't find an iteresting thing!
Is there a savier?
isn't there more and perfectly referene?
I want to know: who does logarithm making easy calculus?
applying logarithms into a complicated function can make the function much easier. for example:
y= [x^(3/4)√ (x² + 1)]/(3x + 2)^5
apply log to both sides
lny = 3/4lnx + 1/2lx(x² + 1) - 5ln(3x + 2)
all we gotta do now is add and subtract which is much easier than the original one.
