An act that is regarded by theologians as a transgression of God's will Ratio of the length of the side opposite the given angle to the length of the hypotenuse of a right-angled triangle (Akkadian) god of the Moon; counterpart of Sumerian Nanna ...
For example, let’s calculate the sine of angle α in a triangle with the length of the opposite side equal to 4 and the hypotenuse equal to 6. sin(α) =4/6 sin(α) =2/3 Sine Graph If you graph the sine function for every possible angle, it forms a repeating up/down curve. ...
Today, we will discuss the sin() function in PHP. This function is used to calculate the sine of an angle.
