Is sin 2x the same as Sinx 2?
Nope. sin²x you take the sine first, then square, in sin(x²), you square the x first then take the sine.
still, What exactly is sine?
In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle (the hypotenuse).
next, What does sin 2x equal?
Sin 2x formula is 2sinxcosx.
then, What is the derivative of sin 2x?
Answer: The differentiation of sin(2x) gives 2cos(2x).
What is the identity of sin 2x?

Why sine is called sine?
The word sine comes from the Latin sinus, bosom, because early translators mistook the Arabic word for chord and thought it was the Arabic word for bosom. The “co-” prefix in cosine and cotangent simply stands for co-angle, the complementary angle. The cosine of an angle is the sine of its complementary angle.
What does a sine curve look like?
The shape of the sine curve is the same for each full rotation of the angle and so the function is called ‘periodic’. The period of the function is 360° or 2π radians. You can rotate the point as many times as you like. This means you can find the sine of any angle, no matter how large.
Who invented sine?
Sine was introduced by Abu’l Wafa in 8th century, as a more convenient function, and gradually spread first in the Muslim world, and then to the West. (But apparently it was used in India centuries before him), as a more convenient function. However this new notation was adopted very slowly, it took centuries.
How do you find sin 2x?

Is cos 2x sin 2x 1 2sin 2x an identity?
Answer: The identity cos2x − sin2x = 1 − 2sin2x is verified.
Is cos 2x sin 2x?
To find the value of sin2x × Cos 2x, the trigonometric double angle formulas are used. For the derivation, the values of sin 2x and cos 2x are used. So, Sin 2x Cos 2x = 2 Cos x (2 Sin x Cos2 x − Sin x)
