In mathematics, sin(x) is a trigonometric function that represents the ratio of the length of the side opposite to a given angle x in a right triangle to the length of the hypotenuse of the triangle
In mathematics, sin(x) is a trigonometric function that represents the ratio of the length of the side opposite to a given angle x in a right triangle to the length of the hypotenuse of the triangle. This function is commonly used in various fields, including physics, engineering, and mathematics itself.
The value of sin(x) can range from -1 to 1, depending on the angle x. Here are some specific values of sin(x) for commonly used angles:
– For x = 0 degrees, sin(0) = 0.
– For x = 30 degrees, sin(30) = 1/2.
– For x = 45 degrees, sin(45) = √2 / 2 or approximately 0.707.
– For x = 60 degrees, sin(60) = √3 / 2 or approximately 0.866.
– For x = 90 degrees, sin(90) = 1.
The graph of sin(x) is a periodic function with a period of 2π (or 360 degrees), which means that the function repeats itself every 2π units. The shape of the graph resembles a wave that oscillates between -1 and 1.
To use sin(x) in calculations, you can either use a scientific calculator or refer to trigonometric tables that provide the values of sin(x) for different angles. It is important to note that the input for sin(x) should be in radians rather than degrees. If you want to convert an angle from degrees to radians, you can use the formula: radians = (π/180) * degrees.
In summary, sin(x) is a trigonometric function that represents the ratio of the opposite side to the hypotenuse in a right triangle. It is widely used in mathematics and other fields to model periodic phenomena and solve various problems involving angles and triangles.
