Hello, what level of math should I have before learning this book?
Basic algebra and little bit of calculus. It won't harm much if you don't know integration, just know differentiation.
Hello, sir. Is the Calculus made easy by Thompson, a good calculus book for beginners like me?
I don't know I did not use that book but I don't think you can go wrong with any book in learning basic calculus.
Yes. It is a very good book. For your purpose, however, this may be a better book.
You should also know basic trigonometry. At least, you should be comfortable with the definitions of sine, cosine and tangent in terms of a right triangle.
Yup. Basically whatever is in this book
Separate names with a comma.
