Here I have added some formulas for logarithmic, hyperbolic functions. Nothing fanciful, but still these are quite useful.

Formulas for logarithmic, hyperbolic functions_compressed

**Formulas for logarithmic, hyperbolic functions**

First of all, I write some basic information about logarithmic functions.

Next, I’ll write down a few formulas on logarithmic functions. Hyperbolic functions will come at the end.

So here it goes!!

**Logarithmic functions**

From now onwards, I’ll write the formulas for These also hold true for

Here are some standard values of some logarithmic functions.

###### Logarithm of functions like

Suppose a function is .

Then natural logarithm of will be

Similarly, if a function has the form the natural logarithm of will be

**Special case**

If then the natural logarithm of will be

**Formulas for hyperbolic functions**

**Definition **

- Hyperbolic sine of is
- Hyperbolic cosine of is
- Hyperbolic tangent of is
- Hyperbolic cotangent of is
- Hyperbolic secant of is
- Hyperbolic cosecant of is

**Formulas for hyperbolic functions by definition**

###### Relations between functions

**Functions of negative arguments**
