sin2x
2sinxcosx
The expression sin2x represents the sine of twice the angle x.
To find the value of sin2x, we can use the double angle formula for sine which states that:
sin2x = 2sinx cosx
where sinx is the sine of the angle x, and cosx is the cosine of the angle x.
Alternatively, we can also express sin2x in terms of the sine of angle x as follows:
sin2x = sin(x+x)
Using the trigonometric identity for the sum of angles, we get:
sin(x+x) = sinx cosx + cosx sinx
= 2sinx cosx
Therefore, sin2x can also be written as 2sinx cosx.
It’s important to note that sin2x will have a value between -1 and 1 regardless of the value of x, as sine has a maximum value of 1 and a minimum value of -1.
