The Mean Value Theorem for double integrals says that if f is a continuous function on a plane region D that is of type Ⅰ or Ⅱ, then there exists a point in D such thatUse the Extreme Value Theorem (14.7.8) and Property 15.3.11 of integrals to prove this theorem. (Use the proof...
句意为:现在所需要的是基本生活必需品的不断的供应。在该句中,主语部分含有一个定语从句,先行词是all,在主句中作主语,因此要用关系代词that。all that is needed=what is needed。 故选D。分析总结。 在该句中主语部分含有一个定语从句先行词是all在主句中作主语因此要用关系代词thatallthatisneededwhatisneeded...
