Yo definite integrals according to me are more solvable cause atleast you can learn the tricks but the real catch here is that the more you prac the more active learning you do and that's how you learn maths, by prac and by calmingly solving the question.
I failed Calculus I first semester, because I basicay didn't do exercises and questions, focus on them, that's what will actually enable you to learn the subject and apply it
I never liked maths much, Chem has nearly always been my favourite. Rn my strength is chem>phy>maths. Even if Im able to solve problems at home, I just fuck up at the centre in maths
its just indefinite but u plug in, itll be long just be confident in ur answer. I know the longer u take on a math problem the more you second-guess yourself to be wrong. Chill and practice and eventually you will be fine always be confident.
when you join college you learn about laplace, applied linear algebra (euler and shit), application of differential equation. be sure you are done with all the concepts of calculus especially, its just the beginning homie.
It's really not so bad if you take it step by step. Find F(x) then find F(b) and F(a) then do F(b) - F(a). If finding F(x) is the issue you just need to practice more.
