First Shifting Theorem statement and proof - YouTube

WebIt makes sense, because normally when we're doing antiderivatives, you just take-- you know, when you learn the fundamental theorem of calculus, you learn that the integral of f with respect to dx, you know, from 0 to x, is equal to capital F of x. So it's kind of borrowing that notation, because this function of s is kind of an integral of y of t. Webthe multiplication with exponential functions. This theorem is usually called the First Translation Theorem or the First Shift Theorem. Example: Because L{cos bt} = 2 2 s b s + and L{sin bt} = 2 s b b +, then, letting c = a and replace s by s − c = s − a: L{e at cos 2bt} = (s a)2 b s a − + − and L{e at sin)bt} = (s a 2 b2 b − ...
