Python | Trigonometric operations in excel file using openpyxl

Last Updated : 21 Aug, 2018

Prerequisite : Adjusting rows and columns of an excel sheet using openpyxl.

Openpyxl is a Python library using which one can perform multiple operations on excel files like reading, writing, mathematical operations and plotting graphs. Let’s see how to perform different Trigonometric operations using openpyxl.

Simple trigonometric functions :

Code #1 : Using simple trigonometric functions in the program.

=SIN(Number) : Returns the sine of an angle. Number is the angle in radians for which you want the sine.
=COS(Number) : Returns the cosine of an angle.
=TAN(Number) : Returns the tangent of an angle.
=CSC(Number) : Returns the cosecant of an angle.
=SEC(Number) : Returns the secant of an angle.
=COT(Number) : Returns the cotangent of an angle.

# import openpyxl module 
import openpyxl 
   
# Call a Workbook() function of openpyxl  
# to create a new blank Workbook object 
wb = openpyxl.Workbook() 
   
# Get workbook active sheet   
# from the active attribute. 
sheet = wb.active 
  
# set the width of the column 
sheet.column_dimensions['A'].width = 20
sheet.column_dimensions['B'].width = 30
sheet.column_dimensions['C'].width = 20
  
# writing to the cell of an excel sheet 
sheet['A1'] = "angles in radian"
sheet['A2'] = 0.1
sheet['A3'] = 0.2
sheet['A4'] = 0.3
sheet['A5'] = 0.4
sheet['A6'] = 0.5
sheet['A7'] = 0.6
  
# mention performing trigonometric operations 
sheet['B1'] = "Applying trigonometric function"
sheet['B2'] = "Sine"
sheet['B3'] = "Cosine"
sheet['B4'] = "Tangent"
sheet['B5'] = "Cosecant"
sheet['B6'] = "Secant"
sheet['B7'] = "Cotangent"
  
# The value in cell C1 to C7 is set to a formula  
# that calculates values for particular radian. 
sheet['C1'] = 'corresponding values'
sheet['C2'] = '= SIN(0.1)'
sheet['C3'] = '= COS(0.2)'
sheet['C4'] = '= TAN(0.3)'
sheet['C5'] = '= CSC(0.4)'
sheet['C6'] = '= SEC(0.5)'
sheet['C7'] = '= COT(0.6)'
  
# save the file 
wb.save("simple_trigonometric.xlsx") 

Output:

Code #2 : Using hyperbolic trigonometric functions in the program.

=SINH(Number) : Returns the hyperbolic sine of a Number.
=COSH(Number) : Returns the hyperbolic cosine of a Number.
=TANH(number) : Returns the hyperbolic tangent of a Number.
=CSCH(Number) : Returns the hyperbolic cosecant of a Number.
=SECH(Number) : Returns the hyperbolic secant of a Number.
=COTH(Number) : Returns the hyperbolic cotangent of a Number.
