sine of 180 degrees

Introduction to the formula of sin function Grammar: SIN (number) Number is the angle, in radians, that requires a sine. Note: If the unit of the parameter is degrees, you can multiply PI ()/180 or use the RADIANS function to convert it to

"Radians and degrees are two different units of the measurement angle. Just like "meters" and "city ruler" are two different units that measure the length.In flash, the angle in rotation is measured in degrees, and the angle in trigonometric

Cosine curveOf course, we don't use arrays here ... Otherwise, there is no technical content.Sine curve is characterized by symmetry, and the left part of the ordinate is from 11 straight down to 1, the corresponding right of the ordinate is from 11

"Reprint" should allow the reader to understand the Fourier analysis without looking at any mathematical formula.Fourier analysis is not only a mathematical tool, but also a mode of thinking that can completely subvert a person's previous worldview.
