limx→0 (e^x-cosx-2x)/x^2-2x 几道AP微积分题目求教!
1 求题目中这个极限的值
2 如果g(x)=∫(上2x下0)f(t)dt 求g'(3)的值?
3 原题是
the number of moose in a national park is modeled by the function M that satisfies the logistic differential equation dM/dt =0.6M(1-M/200),where t is the time in years and M(0)=50,what is lim(t→无穷)M(t)?
4 无穷级数∑(n=1到无穷) n/(n^p +1)收敛 求p取值范围
5 ∫2x/(x+2)(x+1) dx=?我感觉这个题应该用分部积分求解，但是总是就被绕进去了= π
