It means the logarithm to the base e. The number "e" is approximately 2.71828... In other words, if you ask, for instance, "what's the natural logarithm of 100", that's equivalent to asking "to what number must I raise 'e', to get the answer 100". The solution of the equation e^x = 100 in this example.

Derivative of natural log?
y = ln (x) dy/dx = 1/x
What is the derivative of natural log?
d/dx lnx=1/x
What is the derivative of ln cos x?
The derivative of the natural log is 1/x, therefore the derivative is 1/cos(x). However, since the value of cos(x) is submitted within the natural log we must use the chain rule. Then, we multiply 1/cos(x) by the derivative of cos(x). We get the answer: -sin(x)/cos(x) which can be simplified into -tan(x).
If e to the power x equals 0.4634 find x?
the natural log, ln, is the inverse of the exponential. so you can take the natural log of both sides of the equation and you get... ln(e^(x))=ln(.4634) ln(e^(x))=x because ln and e are inverses so we are left with x = ln(.4634) x = -0.769165
The log of a quotient is the log of a numerator divided by the log of the denominator?
For a quotient x/y , then its log is logx - log y . NOT log(x/y)
Derivative of natural log?
y = ln (x) dy/dx = 1/x
What is Two times the natural logarithm?
2 log(x)derivative form:d/dx(2 log(x)) = 2/x
How do you factor x squared minus the natural log of x?
You cannot.
Natural Logarithm?
log base 3 of x = lnx
What is the logarithm of log -1?
Assuming you are asking about the natural logarithms (base e):log (-1) = i x pithereforelog (log -1) = log (i x pi) = log i + log pi = (pi/2)i + log pi which is approximately 1.14472989 + 1.57079633 i
Using natural logarithms 1n x equals 0.29366?
log x = 0.127537
Derivative of log?
The derivative of a log is as follows: 1 divided by xlnb Where x is the number beside the log Where b is the base of the log and ln is just the natural log.
What is the derivative of natural log?
d/dx lnx=1/x
How natural log can be converted into common logaritms?
ln(x) = log10(X)/log10(e)
How would you solve 250 to the x power equals 400000?
250(x) = 400,000 Use logs to base '10' Hence log250^(x) = log400,000 xlog250 = log 400,000 Notirce how the power (x) becomes the coefficient. This is oerfectly correct under 'log' rules. x = log 400,000 / log 250 (NOT log(250/400,000). x = 5.60206 / 2.39794 x = 2.33619689..... ~ 2.33619 to 5 d.p.

How do you convert from natural log to numerical values by taking the exponetial?
If: Ln(A) = X Then: A = ex
