I struggled though math in high school because I hated it. Nearly fifty years later I’m struggling through Tom Apostol’s “Calculus” because I love it.
Mathematics is axiomatic that God is real.
I never struggled with math, but I hated high school math because high school math teachers were incompetent, and university level math is taught by TA’s who are not competent in English, especially at the higher priced universities.
I taught Calculus from Apostle back in 1971. Not an easy text.
That said, calc is a beautiful, powerful thing.
I love Tom Apostol’s Advanced Calculus textbook. All of Apostol’s books are great.
