I recommend Differential and Integral calculus by love and rainville (color red cover ng book na to)
Maganda yung book na yan kasi maraming practice problems and need mo ng practice sa mathematics para mas lalo mong makabisado mga identities and theories about integral and diff cal and maexpose ka sa ibat ibang problems
I Recommend naman yung Elementary Differential Equation by rainville and bedient (yellow cover ng book) maganda din yung book kasi marami din pracrice problems dun
May mga answers na yung practice problems jan kaso wala nga lang solution.
If di mo magets nga explanation sa book pwede mo naman suportahan ng youtube videos I recommend enginerdmath and engineer prof kasi may mga series sila or playlist for diff cal and integral and DE madali mo lang mahahanap and syempremas madali kong magegets kasi tagalog yung pagkakaexplain nila
I recommend din na bumili ka ng hardcopy ng book kesa pdf kasi iba feeling pag hardcopy na book mismo gagamitin mo sa pagrereview kesa sa pdf lang
Yang 2 books lang gamit ko dati nung college kaya palag palag na sa exams
