WebThis function will have some slope or some derivative corresponding to, if you draw a little line there, the height over width of this lower triangle here. So, if g of z is the sigmoid function, then the slope of the function is d, dz g of z, and so we know from calculus that it is the slope of g of x at z. WebMay 24, 2005 · : The derivative of the ramp function is the Heaviside function: R'(t-a) = u(t-a). The ramp function and the unit step function can be combined to greatly simplify complicated discontinuous piecewise functions. This is useful if we are trying to define a function such as:

Solution We first write f in the form Equation 8.4.6 as f ( t) = 2 t + 1 + u ( t − 2) ( t − 1). Therefore L ( f) = L ( 2 t + 1) + L ( u ( t − 2) ( t − 1)) = L ( 2 t + 1) + e − 2 s L ( t + 1) (from Theorem 8.4.
