I know the derivative of u (t) is the delta function, d (x). So when I try solve the derivative I use the chain rule and get: g' (t) = e^ (-t)*u (t) + (1-^e (-t))*d (x) However I get stuck at this point and not sure where to go from here.

The derivative of a unit step function is the impulse functions

WebThe derivative is an important tool in calculus that represents an infinitesimal change in a function with respect to one of its variables. Given a function f (x) f ( x), there are many ways to denote the derivative of f f with respect to x x. The most common ways are df dx d f d x and f ′(x) f ′ ( x). fly jinnah manage booking

Derivative of a step function

WebThe derivative of the Heaviside step function is zero everywhere except at the branching point which is at zero since it does not exist there. This is so because the Heaviside function is composed of two constant functions on different intervals and the derivative of a constant function is always zero.
