These are the formulas of the triangles.The triangle is a right angle of two sharp angles in short.Cos is the cosine theorem, which is the adjacent edge of the acute angle divided by the hypotenuse of the triangle.Sin is the sine theorem, which is

1. Mathematical FunctionsMathematical functions are mainly used to deal with numerical data, the main mathematical functions are: absolute value function, trigonometric function (including sine function, tangent function, cotangent function, etc.),

Matrix learning-Basic Knowledge Previously, I learned about matrices in linear algebra and had some knowledge about the basic operations of matrices. I learned how to use matrices to change images when I used GDI + some time ago, after reading this

ObjectiveHigher mathematics is a basic course for every college student to learn, and it may be the most easily forgotten knowledge after the test.I racked my brains when I was studying high numbers, but I never knew why I was learning. Life and
