Hi, i'm a new user of this forum and i wanted to know how i can use calculus and interpolation in my projects. I'm a student in engineering and i usually do home made electronics and computer programming projects, i would like to include calculus to my projects and understand the practical side of what I'm studying but sometimes in calculus and linear algebra for me it's diffcult to understand the practical aspects of some arguments or theorems. Math for me is really enjoyable when i understand how i can apply the concepts to my projects and my work, i wanted to know : how can i use calculus for my electronics and computer engineering projects ? And why scientists and engineers use interpolation instead of keeping tables ? Does anybody know a good book or web source where i can really learn the full application of the concepts of calculus that i'm studying? Sorry for my bad english.
