"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
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
The SIN function is to compute the sine function. It appears in the default common functions, math, and trigonometric functions of Excel functions.
Sin function grammar form: sin (number)
Sin function Application considerations:
1, number
弧度 = 角度 * Math.PI / 180角度 = 弧度 * 180 / Math.PI
In the JavaScript Math object:The sin () method returns the sine of a number.The tan () method returns a number that represents the tangent of a corner.Math.sin(x)Math.tan(x)Parameter x is required.
This is also for a friend who loves to ask. I don't know if there is any better way.
