sqrt() function is an inbuilt function in Python programming language that returns the square root of any number. Syntax: **math.** **sqrt(x)** Parameter: x is any number such that x>=0 Returns: It returns the square root of the number passed in the parameter.

Cosine Formula

Thus, the cosine of angle α in a right triangle is **equal to the adjacent side's length divided by the hypotenuse**. To solve cos, simply enter the length of the adjacent and hypotenuse and solve.

**Python sin()**

- math. sin(var)
- import math var = 0.36 print(math.sin(var))
- import math a1 = 0.36 b1 = 1 c1 = -1 d1 = -0.36 print("Value for parameter ", a1, " is ", math.
- Value for parameter 0.
- import math a = 'Hello' print(math.cos(a))
- For output: TypeError: must be real number, not str.

sqrt() function is an inbuilt function in Python programming language that returns the square root of any number. Syntax: **math.** **sqrt(x)** Parameter: x is any number such that x>=0 Returns: It returns the square root of the number passed in the parameter.

The cosine is equal to **the adjacent side divided by the hypotenuse** (adj/hyp). (1) Memorize: sine = (opposite side) / hypotenuse. cosine = (adjacent side) / hypotenuse.

Python has also a built-in module called math , which extends the list of mathematical functions. When you have imported the math module, **you can start using methods and constants of the module**.

**Top Trigonometric Functions in Python**

- sin(x) Function. The sine of the value which is passed as an argument to this function is returned.
- cos(x) Function.
- tan(x) Function.
- asin(x) Function.
- acos(x) Function.
- atan(x) Function.
- sin(x) Function.
- cosh(x) Function.

The value of cos 1 degrees can be calculated by constructing an angle of 1° with the x-axis, and then finding the coordinates of the corresponding point (0.9998, 0.0175) on the unit circle. The value of cos 1° is equal to the x-coordinate (0.9998). ∴ **cos 1° = 0.9998**.

**Steps**

- Simplify sin 150° into sin(90° + 60°).
- Further, we can say sin((1 × 90°) + 60°)
- Now as we have an odd coefficient of 90°, sin changes to cos.
- Also, it is covering 90° in the first quadrant and again added 60° leads to the second quadrant.
- The final result will be cos 60°.

cos() function. In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. math. cos() function **returns the cosine of value passed as argument**.

acos() Function in Python. First of all, we need to **import the math library and then apply math.** **acos() function to our input value to find the inverse of cosine**. Inverse of cosine using the acos() function gives the result in radians.

**Use the scipy Module to Calculate the Cosine Similarity Between Two Lists in Python**. The spatial. cosine. distance() function from the scipy module calculates the distance instead of the cosine similarity, but to achieve that, we can subtract the value of the distance from 1.

**Mathematical Functions in Python | Set 3 (Trigonometric and Angular Functions)**

- sin() :- This function returns the sine of value passed as argument.
- cos() :- This function returns the cosine of value passed as argument.
- tan() :- This function returns the tangent of value passed as argument.

Python cos() is an inbuilt method defined under the math module, which is used to find the cosine value of the parameter passed in radians. We can use the math module by importing it. The syntax for it would be **import math;** after importing, we use to call this function using the static object.

What is math module in Python? The math module is a standard module in Python and is always available. To use mathematical functions under this module, **you have to import the module using import math** .
