## LollyLau 4 years ago Is log used in calculus? Is it the same is ln?

1. amistre64

a naked log tends to mean base 10, whereas ln referes to base "e"

2. amistre64

calculus likes to convert things into ln

3. amistre64

change of base:$log_{10}(x)=\frac{ln(x)}{ln(10)}$

4. LollyLau

Sometimes people tend to write log. Is that considered wrong?

5. amistre64

the wolf likes to use log for ln, so i doubt its "wrong"

in my country log can be any base, lg is used for base 10 and ln is used for base e

7. amistre64

as long as the meaning is defined before hand to clarify any misconceptions

8. LollyLau

"confused"
