Without computer or tables, but just using facts you know, sketch a quick rough graph of the function from -2to 3. Hint:This is easy; don’t make a big job of it. From Section 3, you know the values of the data-custom-editor="chemistry" function at the positive integers in terms of factorials. From Problem 1, you can easily find and plot the function at , . (Approximateas a little less than 2.) From (4.1) and the discussion following it, you know that the function tends to plus or minus infinity at 0 and the negative integers, and you know the intervals where it is positive or negative. After sketching your graph, make a computer plot of the Γ function from -5to 5and compare your sketch.
In the pendulum problem, is an approximate solution when the amplitude α is small enough for the motion to be considered simple harmonic. Show that the corresponding exact solution when α is not small is is the modulus of the elliptic function. Show that this reduces to the simple harmonic motion solution for small amplitude α
Express the following integrals as functions, and then, by , in terms of functions. When possible, use function formulas to write an exact answer in terms of , etc. Compare your answers with computer results and reconcile any discrepancies. .
