| So I have an expression called "y" in the form X+i*Y. I need to get X and Y respectively as separate expressions. Obviously, Re[y]=X and Im[y]=Y. But for some reason functions Re[] and Im[] do not return what I expect. Even though I explicitly... |
| So I wanted to replace i with 0 in my equation (pls don't ask why). I tried several options but none of them gave the result I wanted. What should I do?![showcase of the problem][1] [1]:... |
| For some reason Mathematica keeps returning dots in between variables and their coefficients. So instead of "1000s" I get "1000.s". And even more weird, instead of "2500" I get "2500.". Why is it happening and how do I get rid of it? |
| So I declare a complex function r[w] and I want to create another function U[w] which is defined by the real part of r[w]. So I try to use the embedded Re[] function but it returns a weird expression. r[w]=200/(I*w*(10*I*w + 1)) If I do... |
| Thanks a lot, Alexander! |
| Thanks! I gained a lot of knowledge:) |
