Semnan University International Journal of Nonlinear Analysis and Applications 2008-6822 13 2 2022 07 01 Solving differential equations and integral problems using wavelets 1553 1563 6504 10.22075/ijnaa.2022.6504 EN Ali Naji Shaker Directorate of Scholarships and Cultural Relations, Ministry of Higher Education and Scientific Research of Iraq, Baghdad, Iraq Journal Article 2021 04 03 Due to benefit of wavelets through numerical and other estimation methods and edge through Fourier analysis, the wavelet hypothesis has expanded broad significance at the time of previous years basically because of their application in comparing areas of science and masterminding, for instance, viscoelasticity, scattering of a natural people, signal taking care of, electromagnetism, fluid mechanics, electrochemistry, and some more. Wavelet has been fundamentally a wave design whose graph oscillates just through a short separation and dumps extremely quick. It tends to be utilized as equipment for taking care of such mathematical problems as differential conditions and integral issues. We have been utilizing wavelet techniques for fathoming the request differential condition; likewise, consider their accuracy and efficiency. https://ijnaa.semnan.ac.ir/article_6504_60b1071ae54f3f7adb5efba1b4ba871e.pdf
