Komplekse tal i Python | Sæt 2 (vigtige funktioner og konstanter)
Introduktion til python komplekse tal: Komplekse tal i Python | Sæt 1 (introduktion) Nogle vigtigere funktioner og konstanter diskuteres i denne artikel. Operationer på komplekse tal : 1. exp() :- Denne funktion returnerer eksponent af det komplekse tal nævnt i sin argumentation. 2. log(xb) :- Denne funktion returnerer logaritmisk værdi af x med grundtallet b both mentioned in its arguments. If base is not specified natural log of x is returned. Python
# Python code to demonstrate the working of # exp() log() # importing 'cmath' for complex number operations import cmath import math # Initializing real numbers x = 1.0 y = 1.0 # converting x and y into complex number z = complex ( x y ); # printing exponent of complex number print ( 'The exponent of complex number is : ' end = '' ) print ( cmath . exp ( z )) # printing log form of complex number print ( 'The log(base 10) of complex number is : ' end = '' ) print ( cmath . log ( z 10 ))
Output: The exponent of complex number is : (1.4686939399158851+2.2873552871788423j) The log(base 10) of complex number is : (0.15051499783199057+0.3410940884604603j)3. log10() :- Denne funktion returnerer log base 10 af et komplekst tal. 4. sqrt() :- Dette beregner kvadratrod of a complex number. Python
# Python code to demonstrate the working of # log10() sqrt() # importing 'cmath' for complex number operations import cmath import math # Initializing real numbers x = 1.0 y = 1.0 # converting x and y into complex number z = complex ( x y ); # printing log10 of complex number print ( 'The log10 of complex number is : ' end = '' ) print ( cmath . log10 ( z )) # printing square root form of complex number print ( 'The square root of complex number is : ' end = '' ) print ( cmath . sqrt ( z ))
Output: The log10 of complex number is : (0.15051499783199057+0.3410940884604603j) The square root of complex number is : (1.09868411346781+0.45508986056222733j)5. isfinite() :- Returnerer sand, hvis både ægte og imaginær del af komplekse tal er endelig ellers returnerer falsk. 6. Til dig() :- Returnerer sand, hvis enten en reel eller imaginær del af komplekst tal er/er uendelig ellers returnerer falsk. 7. isnan() :- Returnerer sandt hvis enten ægte eller imaginær del af komplekst tal er NaN else returns false. Python
# Python code to demonstrate the working of # isnan() isinf() isfinite() # importing 'cmath' for complex number operations import cmath import math # Initializing real numbers x = 1.0 y = 1.0 a = math . inf b = math . nan # converting x and y into complex number z = complex ( x y ); # converting x and a into complex number w = complex ( x a ); # converting x and b into complex number v = complex ( x b ); # checking if both numbers are finite if cmath . isfinite ( z ): print ( 'Complex number is finite' ) else : print ( 'Complex number is infinite' ) # checking if either number is/are infinite if cmath . isinf ( w ): print ( 'Complex number is infinite' ) else : print ( 'Complex number is finite' ) # checking if either number is/are infinite if cmath . isnan ( v ): print ( 'Complex number is NaN' ) else : print ( 'Complex number is not NaN' )
Output: Complex number is finite Complex number is infinite Complex number is NaNKonstanter Der er to konstanter defineret i cmath-modulet 'pi' som returnerer den numeriske værdi af pi. Den anden er 'og' which returns the numerical value of exponent. Python
# Python code to demonstrate the working of # pi and e # importing 'cmath' for complex number operations import cmath import math # printing the value of pi print ( 'The value of pi is : ' end = '' ) print ( cmath . pi ) # printing the value of e print ( 'The value of exponent is : ' end = '' ) print ( cmath . e )
Output: The value of pi is : 3.141592653589793 The value of exponent is : 2.718281828459045Komplekse tal i Python | Sæt 3 (trigonometriske og hyperbolske funktioner)
