Hi I am going to finish my calculus sequences with this semester [1,2&3 (Vector Cal)]. Currently I am enrolled in Computer Science program in my university. I am interested to study about Analysis. I need some clarifications about Analysis. Please guide me... My questions are: 1. What is Analysis ? Is Mathematical Analysis and Analysis are same? 2. Do people use it real life ? 3. What topics in Mathematics I should study to become an Analyst[?] ? Should I change my major to Math or Is it possible to do it with Comp Sci? PS: I have completed my Linear Algebra course. Differential Equations - I didn't take it yet!! Thank you. Excuse my English.
