NettetAn integral has two bounds: a lower bound and an upper bound. If you’re given an integral, you’ll be integrating between these two bounds. The lower bound is where you start integrating. You’ll find it underneath the integral symbol: The upper bound is the line at which you stop integrating. It’s above the integral symbol: Nettet9. jun. 2024 · Fractional differential equations arise from various applications including in a variety of fields of mathematical and natural science.
