What is a good website for math answers?

Answer 1

Usually there isn't any one website for math answers. So you should probably Google whatever math question you have. For example, if you're working with sin, cos and tan, then you should look up "sin calculator", "cos calculator" or "tan calculator" or a variant depending on what you need help with, like "explanation of tan".

Answer 2

Math was a tough subject for me so finding a resource to help my kids was a necessity. Some I recommend are: webmath dot com and cool math dot com.
