In this tutorial we will learn the list of Trigonometric functions and how to effectively utilize the Trigonometric functions for the purpose of trigonometric operations that we require.

**PI Function in Excel: **PI function in Excel returns the value of the mathematical constant pi (π). PI function in Excel returns the PI value with 15 digits (14 decimal places).

**SQRTPI Function in Excel: **SQRTPI function in Excel returns the value of the Square root of mathematical constant pi (π) multiplied by supplied number. SQRTPI(number) is same as SQRT(π*number)

**DEGREES Function in Excel: **DEGREES Function in Excel converts the angle in radians to degrees

**RADIANS Function in Excel: **RADIANS Function in Excel converts the angle in degrees to radians.

**COS Function in Excel: **The COS function in Excel calculates and returns the cosine of a given radians.

**ACOS Function in Excel: **The ACOS function in Excel calculates the arccosine (inverse of cosine) of a given number and returns the angle in radians between 0 and π. Arccosine is inverse of cosine.

**SEC Function in Excel: **The SEC function in Excel calculates and returns the secant of a given radians. The Secant is the reciprocal of Cosine.

**SIN Function in Excel: **The SIN function in Excel calculates and returns the sine of a given radians.

**CSC Function in Excel: **The CSC function in Excel calculates and returns the cosecant of a given radians. Cosecant is reciprocal of sine.

**TAN Function in Excel: **The TAN function in Excel calculates and returns the Tangent of a given radians

**COT Function in Excel: **The COT function in Excel calculates and returns the cotangent of a given radians. COT is the reciprocal of TAN

**ASIN Function in Excel: **The ASIN function in Excel calculates the arcsine (inverse of sine) of a given number and returns the angle in radians between 0 and π. Arcsine is inverse of sine.

**ATAN Function in Excel: **The ATAN function in Excel calculates the arctan (inverse of Tan) of a given number and returns the angle in radians between 0 and π. Arctan is inverse of tan.

**ACOT Function in Excel: **The ACOT function in Excel calculates the arccot (inverse of cot) of a given number and returns the angle in radians between 0 and π. Arccot is inverse of cot.

**Exponential Function in Excel: **The Exponential function in Excel (EXP) calculates the value of the mathematical constant e, raised to the power of a given number.

**LN() Function in Excel: **LN Function in Excel calculates the natural logarithm of a given number. The Natural Logarithm of a number, (Ln(x) or Log_{e}(x)), is the logarithm to the base

**LOG Function in Excel: **LOG function in Excel calculates the logarithm of a given number, to a supplied base

**If a ^{x} = b Then Log_{a}(b) = x**

**LOG10 Function in Excel: **LOG10 function in Excel calculates the common logarithm i.e. logarithm of a given number, to the base 10.

**If 10 ^{x} = b Then Log_{10}(b) = x**

**FACT Function in Excel: **Fact function in Excel returns the factorial of a given number. The Factorial of a number, N, is given by the product – **N * (N-1) *(N-2) …3 * 2 * 1.**

** **

**FACTDOUBLE Function in Excel: **FACTDOUBLE Function in Excel returns the double factorial of a given number. Double Factorial can be calculated as follows.

- If N is even then Double Factorial of N will be

** N * (N-2) * (N-4) * …. 6* 4 * 2**

- If N is odd then Double Factorial of N will be

** ****N * (N-2) * (N-4) * ….5 * 3 * 1**

** **

**Multinomial Function in Excel: **Multinomial function in Excel calculates the ratio of the factorial of a sum of supplied values to the product of factorials of those values.

**i.e. Multinomial (x**_{1}**,x**_{2}**,x**_{3}**….x**_{n}**)= (x**_{1}**+x**_{2}**+x**_{3}**….+x**_{n}**)/ x**_{1}**!x**_{2}**!x**_{3}**!….x**_{n}**!**

**COMBIN Function in Excel: **The COMBIN function in Excel calculates the number of combinations of a given number objects from the set without repetition.

For any 4 objects a,b,c,d there are 6 different combination of two objects

ab |
ac |
ad |
bc |
bd |
cd |

**COMBINA Function in Excel: **The COMBINA function in Excel calculates the number of combinations of a given number objects from the set with repetition.

For any 4 objects a,b,c,d there are 10 different combination of two objects

ab |
ac |
ad |
bc |
bd |
cd |
aa |
bb |
cc |
dd |
