Hello, I'm going to begin undergraduate study next year (majoring in physics) and I have not taken any calculus yet. What I'm wondering is, with calculus can you check that your answer is right? Like with algebraic problems you can plug a variable back into your original equation and see if it comes out equivialent. This is just something I'm curious about and probably is a stupid question which stems from my ignorance of calculus. Anyways, thanks for any responses.
