Q:

# What is the equation "sin x squared"?

A:

The equation "sin x squared" may refer to the equations sin(x^2) or (sin(x))^2, which is the same as sin2(x). Using trigonometric identities, sine-squared of x can be used in the equations sin2(x) = 1/2 - 1/2 cos(2x), sin2(x) + cos2(x) = 1 and (cos(x))^2 = 1 - 2sin2(x).

The equation "sin x squared" uses the trigonometric function sine, which is defined as a ratio between particular sides of a right triangle. In the equation, x represents the value of an angle expressed in either degrees or radians. The sine function, along with the cosine and tangent functions, is commonly used in geometry. They can be evaluated manually or with a calculator.
