Addition and difference formulas exist for sine, cosine, and tangent functions in trigonometry. In this type of formula, two angles are either in sum form or in difference form. These are used for proving some unknown identities, simplifying expressions, and many more. The formulas are: ...
Then, ifxis very small you can neglect all term of order greater than one getting: You can also show this result using basic trigonometry but this approach seems easier to me. 还有一个答案是: You can give a linear approximation forsinnear0based on this formula: and using the fact that:s...
