tutorials, solutions, and so on. In addition, Wolfram Research also provides professional technical support and services to help users solve problems encountered in the use.总之
Mathematica can be used to solve problems involving complex symbolic and numerical calculations in various fields, such as various calculations of polynomials, including operations, expansions, and decompositions; it can also find exact and approximate solutions of various equations, and the limit of fun...
(-(v/f) - (P Log[P - f v])/f^2)PS:由于尝试直接计算v[t]时出现如下提示：Solve::ifun: Inverse functions are being used by Solve, so some solutions may not be found; use Reduce for complete solution information. >> 所以应想到求其逆函数，但函数关系不变。望有所帮助。
