Mathematical diagrams and equations.
I am writing a math book which requires step by step diagrams and explanations.
I have tried writing these by hand, then taking a picture, adjusting it, then inserting into the word document.
This sounds like it would work, but the white background turns to grey and looks horrible inside the document.
I have tried using red paper, (OK) lilac ( not ok) to handwrite my diagrams. Lulu rejected the idea of printing each page and entering the handwritten part, then scanning the result.
What do others think or know?
