Vor 4 Tagen · the interchange of a derivative and an integral (differentiation under the integral sign; i.e., Leibniz integral rule); the change of order of partial derivatives; the change of order of integration (integration under the integral sign; i.e., Fubini's theorem ).
Vor 6 Tagen · A function which is the product of two different kinds of functions, like xe^x, xex, requires a new technique in order to be integrated, which is integration by parts. The rule is as follows: \int u \, dv=uv-\int v \, du ∫ udv = uv −∫ vdu. This might look confusing at first, but it's actually very simple.
Vor 5 Tagen · By the integral definition, the relation (+) = and Hadamard factorization theorem, 1 Γ ( z ) = z e c 1 z + c 2 ∏ n = 1 ∞ e − z n ( 1 + z n ) , z ∈ C ∖ Z 0 − {\displaystyle {\frac {1}{\Gamma (z)}}=ze^{c_{1}z+c_{2}}\prod _{n=1}^{\infty }e^{-{\frac {z}{n}}}\left(1+{\frac {z}{n}}\right),\quad z\in \mathbb {C} \setminus ...

Vor 6 Tagen · 4 Antworten. Dem Integral einer Funktion f (x) nähert man sich über die Untersumme / Obersumme von Rechtecksflächen an. Je schmaler die Rechtecksflächen werden, desto grösser ist deren Anzahl, und um so besser näheren sich Untersumme/Obersumme dem Wert des Integrals an. Es gilt.

Vor 2 Tagen · To find the Laplace transform of this little f, we just write down the definition. So by definition, this big F of s is the integral from 0 to infinity f of t e to the negative s t dt. And since it is 0 when t is less than 7, so we integrate from 7 to infinity. t and when t is greater than or equal to 7 little f of t is t minus 7 to the power ...
Vor einem Tag · In addition, for the homogeneous system it is established that the weighted stability in the Lyapunov and Ulam–Hyers senses are equivalent if and only if the inequality appearing in the Ulam–Hyers definition possess only bounded solutions. Finally, we derive natural sufficient conditions under which the property of weighted global asymptotic stability of the zero solution of the ...
