Answer 2

The expression "Sin3x" represents the sine function of an angle 3 times x (where x is typically an angle measured in radians). Mathematically, it can be written as:

Sin(3x)

In trigonometry, the sine function (Sin) takes an angle as input and gives the ratio of the length of the side opposite to the angle to the length of the hypotenuse in a right-angled triangle. However, when dealing with the sine function as an algebraic expression, it represents the y-coordinate of a point on the unit circle corresponding to the angle.

For example, if you have to find the value of Sin(3x) for a specific value of x, you would evaluate the sine function at 3 times that value of x. The result will be a number between -1 and 1, representing the sine of the angle 3x.
