2013年4月27日 · Now my question it's about the first ecuation, because I write the code like in (1) to see the solution and this "csgn(z)" freak me out, so I asking does this csgn change my result where 0. Why did it appear, it's because Maple doesn't know the values of z? I hope someone can help me, Greetings

2016年11月18日 · Hi, I was wondering why when I want to equate Maple returns. I know that the maple arctan(x,y) (or atan2) plots from Pi/..-Pi/2, but at x = 0, depending on the sign of y, it should either return Pi/2 or -Pi/2. but the equation returned wouldnt do that, It …

I am getting correct answers but with some notation that I know will confuse my students. the second line gives an answer that contains the CSGN notation . I have the Meade et al book that shows the example . simplify (sqrt(x^2),symbolic ) which overcomes this problem. But it …

2020年12月23日 · For the case when the output of odetest contains one csgn(), I am trying to determine if odetest result will become zero, when csgn is +1 or -1. If so, then next look into the argument of csgn and solve for x under this condition and hence find the range of x when the solution is valid. I wrote the following to do this and check the idea.

To my knowledge csgn appears when assumptions are not correctly specified - is this so? I can't see any assumption that I would need to specify and the ones I have tried have made no difference (beta is real, k is an integer, sigma >= 0) .

2011年2月24日 · csgn(conjugate(sigma)) and [infinity, otherwise] in it. I want to apply a rule to the output (1) to simplify the exponential terms into cosine term. But I am thinking that the reason my rule fails is because of the presence of the csgn, infinity otherwise expressions in the output.
