I am not exactly sure where you can learn but where to start basically is whom are know for their engineering majors specifically computer science, mechanical or industrial engineering will for sure include applied mathematics also other social studies will include this (idk which exactly youre looking for so just spitballin here😅) also based on the major you're on, applied mathematics may continue till applied mathematics 3 so ready up🫡 I hope this helps🤞🏽
