Nyob zoo cov phooj ywg! Zoo siab heev uas tau ntsib koj hnub no. Hnub no, peb yuav tham txog **Python Math Library**, uas yog ib yam khoom siv tseem ceeb rau kev ua lej. Yog tias koj yog ib tug neeg pib kawm txog kev siv Python, tsis txhob txhawj. Kuv yuav piav meej txog qhov no rau koj thiab muab cov piv txwv nrog rau cov txiaj ntsig koj tuaj yeem sim tau koj tus kheej.
Python Math Library
Python Math Library yog ib qhov cuab yeej muaj zog uas pab koj ua tau ntau yam haujlwm lej yooj yim thiab sai heev. Nws muaj ntau yam kev ua haujlwm xws li kev suav lej yooj yim, trigonometria, logarithms, thiab ntau ntxiv. Peb cia li saib qee yam haujlwm no kom koj nkag siab zoo dua.
import math # 1. Qhov txiaj ntsig ntawm π (pi) pi_value = math.pi print("Qhov txiaj ntsig ntawm pi: ", pi_value) # 2. Cov haujlwm trigonometria: sin, cos, tan degree = math.radians(30) # Hloov deg rau radians sin_value = math.sin(degree) cos_value = math.cos(degree) tan_value = math.tan(degree) print("sin(30°): ", sin_value) print("cos(30°): ", cos_value) print("tan(30°): ", tan_value) # 3. Logarithms log_value = math.log(10) print("Logarithm ntawm 10: ", log_value) # 4. Phem square root sqrt_value = math.sqrt(16) print("Phem square root ntawm 16: ", sqrt_value) # 5. Absolute txiaj ntsig abs_value = math.fabs(-5) print("Absolute txiaj ntsig ntawm (-5): ", abs_value)
Txiaj Ntsig ntawm Cov Piv Txwv:
Qhov txiaj ntsig ntawm pi: 3.141592653589793 sin(30°): 0.49999999999999994 cos(30°): 0.8660254037844387 tan(30°): 0.5773502691896257 Logarithm ntawm 10: 2.302585092994046 Phem square root ntawm 16: 4.0 Absolute txiaj ntsig ntawm (-5): 5.0
Zoo li koj pom, math library muaj ntau hom haujlwm rau kev ua lej. Hauv cov piv txwv saum toj no, peb siv cov haujlwm zoo li sin, cos, tan, thiab log.
Piv txwv: Cheeb tsam ntawm Lub Voj
Tam sim no, peb yuav ua ib qho piv txwv tshiab kom koj nkag siab zoo dua. Peb yuav xam tus cheeb tsam ntawm ib lub voj siv cov math library. Cov qauv no yog (A = π \cdot r2), uas (r) yog lub voj kab.
def area_circle(radius): return math.pi * math.pow(radius, 2) radius = 5 area = area_circle(radius) print(f"Cheeb tsam ntawm lub voj uas muaj txoj kab {radius}: {area}")
Txiaj Ntsig:
Cheeb tsam ntawm lub voj uas muaj txoj kab 5: 78.53981633974483
Xaus Lus
Peb tau kawm tias Python Math Library yog ib qho cuab yeej muaj zog rau kev suav lej thiab ua rau koj txoj haujlwm ua lej yooj yim dua. Yog tias koj xav paub ntxiv txog kev siv Python, nws yog ib qho zoo siab kawm txog ntau yam haujlwm ntxiv hauv cov library no. Python tsis yog tsuas yog ib qhov kev siv, nws tseem yog ib qho cuab yeej uas muaj ntau yam kev pab hauv ntau yam haujlwm.
Ua tsaug ntau rau koj tus kheej uas tau tuaj nyeem txog no! Kuv vam tias qhov no yuav pab koj nkag siab txog math library hauv Python thiab txhawb koj kev kawm kom txaus siab ntxiv!
