What is the right triangle definition of the sine function?
Herein, what is the sin of a right triangle?
Sine (sin) function - Trigonometry. In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse.
Hereof, what is the sine of an angle?
In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).
Let's start with the basic sine function, f (t) = sin(t). This function has an amplitude of 1 because the graph goes one unit up and one unit down from the midline of the graph. This function has a period of 2π because the sine wave repeats every 2π units.
