理解空間曲面方程的概念,能求出空間動(dòng)點(diǎn)的軌跡方程7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單在空間取三條相互垂直且相交于O點(diǎn)的數(shù)軸構(gòu)成空間直角坐標(biāo)系.這三條數(shù)軸依次稱為x

軸(橫軸)、y

軸(縱軸)、z

軸(豎軸),三條軸統(tǒng)稱為坐標(biāo)軸,點(diǎn)O稱為坐標(biāo)原點(diǎn).習(xí)慣上,我們把x

軸、y

軸置于水平面上,而z軸取垂直向上方向,如圖7—2所示.觀看圖7—3,我們可以想象,y

軸和z軸是落在紙面上的,而x

軸是垂直于紙面指向我們,它們的方向滿足右手法則.所謂右手法則,指的是:伸出右手,使拇指的指向與其他四指垂直,當(dāng)四指從x

軸的正向轉(zhuǎn)向y

軸正向時(shí)拇指的指向就是z

軸的正向.按右手法則確定的坐標(biāo)系稱為右手系.本章用的坐標(biāo)系都是右手系.7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用例題解析第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用例題解析第七章多元函數(shù)微積分初步ppt課件7.1空間曲面節(jié)菜單7.1空間曲面7.2多元函數(shù)的極值與連續(xù)7.3偏導(dǎo)數(shù)7.4二元函數(shù)的極值與連續(xù)7.5二重積分與應(yīng)用第七章多元函數(shù)微積分初步ppt課件在平面解析幾何中,我們把平面曲線視作動(dòng)點(diǎn)的軌跡.同樣,在空間解析幾何中,任何曲面(包括平面)都看作是動(dòng)點(diǎn)的運(yùn)動(dòng)軌跡(或點(diǎn)的集合),如圖7—8所示.在這個(gè)意義下,曲面所具有的性質(zhì)是它的一切點(diǎn)所共有的.設(shè)(x,y,z)是曲面上的任意一點(diǎn),我們用x,y,z
