When should I use graphical convolution instead of direct integration?
Graphical convolution can be used in any case, but the mathematical method seems much more simpler and quicker, and I noticed that graphical isn't used much at all in non-electrical engineering courses. Is that because we assume that f(t) and h(t) = 0 for t<0 for math examples?- sed199

But in most math and physics courses graphical convolution isn't used. Is that because it's assumed that h(t) and f(t) are assumed to equal 0 for t<0?- sed199

When should I use graphical convolution instead of direct integration?
As a double major in physics an electrical engineering, I noticed that graphical convolution is used in both signal processing and quantum mechanics. In my signals course I couldn't help but notice that sometimes the professor would just convolved the function from straight integration, and...- sed199

Graduate If we have a mass function of time i.e M(t) then F=(m.v') or F=(m.v)' and why ?
by definition, force is the change in momentum with respect for time. Momentum is defined as p=mv. If we are to assume m as constant, as it convieniently is in most cases, f=d(p)/dt=d(mv)/dt=m(dv/dt)=ma But if M was a function of time and represented as m(t), we are stating that mass may...
