举一反三
- 设为正向圆周,为负向圆周,则积分 的值为 /sqp/img?f=082dd162a7e1b0159a2edaf7b9917676.files%2Fimage021.png/sqp/img?f=082dd162a7e1b0159a2edaf7b9917676.files/image022.png/sqp/img?f=082dd162a7e1b0159a2edaf7b9917676.files%2Fimage023.png/sqp/img?f=082dd162a7e1b0159a2edaf7b9917676.files/image024.png/sqp/img?f=082dd162a7e1b0159a2edaf7b9917676.files%2Fimage025.png
- 若是由抛物线与直线所围的闭区域, 在上连续,则 ____/sqp/img?f=0a08d1103a8caee030e6ba8042c26667.files%2Fimage001.png/ananas/latex/p/7563/sqp/img?f=0a08d1103a8caee030e6ba8042c26667.files%2Fimage003.png/ananas/latex/p/147/sqp/img?f=0a08d1103a8caee030e6ba8042c26667.files%2Fimage001.png/sqp/img?f=0a08d1103a8caee030e6ba8042c26667.files%2Fimage005.png
