Hi everyone, I'm currently looking for a book on ways to sketch curves, especially for the more unusual kinds of curves, something that teaches things like hyperbolic curves, x^x, sigmoid functions and so on. These are what I have not encountered in my learning very often, so I'm interested to find out more on these. Are there any good books that teaches these curves and the way to draw it? Any book that shows lots of curves like these alone is good too. Thank you guys!
