解答
积分区域为圆:x^2+y^2=2Ry在第1象限的部分
化为极坐标形式为:
∫dy∫f(x^2+y^2)dx
=∫(0,π/2)dθ∫(0,2Rsinθ)rf(r^2)dr
推荐
- 化为极坐标形式的二次积分:∫[0,1]dx∫[0,1]f﹙x,y﹚dy
- 化下列二次积分位极坐标形式的二次积分 ∫dx∫f(x,y)dy (0
- ∫(0->1)dx∫(x^2->x)(x^2+y^2)^(-1/2)dy化为极坐标形式的二次积分为多少?其值为多少?
- 把二重积分化为极坐标形式的二次积分 ∫dx∫f(x,y)dy 其中∫dx和∫f(x,y)dy的积分上下限都为【0,1】
- ∫(0,2)dx ∫(0,x)f「(x^2+y^2)^(1/2)」dy把积分转换为极坐标形式的,这里的p要怎么取
