Please ensure that your password is at least 8 characters and contains each of the following: You'll be able to enter math problems once our session is over. Algebra Examples Popular Problems Algebra As told by @randomgirl, the slope is matching at x = 0, so, no matter which side function you take it will. Determine if the following piecewise defined function is differentiable at x = 0. f (x) = {2 x 4, x 2 + 4 x 4, x 0 x < 0 What is the right-hand derivative of the given function? The derivative of a constant is equal to zero, hence the derivative of zero is zero. The Heaviside step function is a mathematical function denoted , or sometimes or (Abramowitz and Stegun 1972, p.1020), and also known This means that the slope of the tangent is equal from both sides, so the derivative exists. Example where they don't match up is $g(x)=|x|$ at $x=0$ so $g'$ wouldn't exist at $x=0$. The procedure to use the Laplace transform calculator is as follows: Step 1: Enter the function, variable of function, transformation variable in the input field. First, the Input can be interpreted as the Laplacian of the piecewise function: L [ { t 1 1 t < 2 t + 1 t > 2 } ( s)] The result is given after the Laplace Transform is applied: e 2 s ( 2 s + e s) s 2.
