sin(-x)
The sine function, denoted as sin(x), is a mathematical function that relates the angle x in a right triangle to the ratio of the length of the side opposite the angle to the length of the hypotenuse
The sine function, denoted as sin(x), is a mathematical function that relates the angle x in a right triangle to the ratio of the length of the side opposite the angle to the length of the hypotenuse. It is defined for all real numbers.
Now, let’s consider sin(-x). When we put a negative sign in front of the angle, it represents the negative of that angle. In other words, sin(-x) is equal to the negative of sin(x).
Geometrically, this can be understood as follows: if we have an angle x in a right triangle that corresponds to a certain sine value, then the angle -x will be the same as angle x but in the opposite direction. Thus, the sine values will have opposite signs.
For example, let’s say sin(x) = 0.5, meaning the angle x corresponds to a sine value of 0.5. In this case, sin(-x) will be -0.5, as the negative sign reverses the sign of the sine value.
In summary, sin(-x) is the negative of sin(x), meaning the sine value of the angle -x is equal to the opposite sign of the sine value of the angle x.
