[發問] 三個Mathematica的問題請求幫助
請各位專家幫忙提示我該如何解題感激不盡
題目如下, 請高手幫幫忙 ^^
1. Write a function that as input has an expression f, and returns the logarithmic derivate 1/f (d f)/(d x) . Use a conditional or pattern test to make your function accept any symbols as input except for lists.
2.
a) Write a recursive function that computes the function f defined by 6 n f=f+n! for n>0, and f=7. Restrict the argument to positive integers.
b) Write and test a program that computes f using Module and a While loop.
c) Compare the timings of the two methods by computing f in both cases for very large values of n and/or doing the computation many times. You may have to use Clear or restart to clear Mathematica's memory of previous calculations. Explain your results.
Consider the iterative map Subscript == 1/2 Subsuperscript -\.
a) Compute its fixed points and 2-cycles as a function of \.
b) Using linear stability analysis, compute the range of stability of both the fixed points as well as the 2-cycles.
c) Show cobweb diagrams for representative parameters illustrating the (un)stable fixed point and 2-cycle.
d) Graphically demonstrate the onset of a stable 3-cycle.
e) Produce the bifurcation diagram. 似乎貼的不是很好...
