  # Python | function math.tan ()

NumPy | Python Methods and Functions

In Python, a math module contains a number of math operations that can be easily accomplished using the module. `math.tan() ` returns the tangent of the value passed as an argument. The value passed to this function must be in radians.

Syntax: math.tan (x)

Parameter:
x: value to be passed to tan ()

Returns: Returns the tangent of value passed as argument

Code # 1:

 ` # Python code for tan () demonstration `   ` # import & quot; math & quot; for math operations ` ` import ` ` math `   ` a ` ` = ` ` math.pi ` ` / ` ` 6 `   ` # returning the tangent of pi / 6 ` ` print ` ` (` ` "The value of tangent of pi / 6 is:" ` `, end ` ` = ` ` "") ` ` print ` ` (math.tan (a)) `

Code # 2:

 ` # Show Python program `  ` # Graphical representation ` ` # tan () function ` ` import ` ` math ` ` import ` ` numpy as np ` ` import ` ` matplotlib.pyplot as plt `   ` in_array ` ` = ` ` np.linspace (` ` 0 ` `, np.pi, ` ` 10 ` `) `   ` out_array ` ` = ` ` [] `   ` for ` ` i ` ` in ` ` range ` ` (` ` len ` ` (in_array)): ` ` out_array.append (math.tan (in_array [i])) ` ` ` ` i ` ` + ` ` = ` ` 1 `     ` print ` ` (` ` "in_array:" ` `, in_array) ` ` print ` ` (` ` " out_array: "` `, out_array) ` ` `  ` # red for numpy.sin () ` ` plt.plot (in_array, out_array, color ` ` = ` `` red` ` < code class = "plain">, marker ` = ` ` "o" ` `) ` ` plt.title (` ` "math.tan ()" ` `) ` ` plt.xlabel (` ` "X" ` `) ` ` plt.ylabel (` ` "Y" ` `) ` ` plt.show () `
