cos(2x) = 1 - 2(sin(x)^2), so sin(x)^2 = 1/2 - 1/2*cos(2x).

No.
Do sin(x), square it, and then multiply it by two.
Yes. Except where sin x = 0, because then you would be dividing by zero so the quotient is undefined.
The deriviative of sin2 x + cos2 x is 2 cos x - 2 sin x
Answer 1 Put simply, sine squared is sinX x sinX. However, sine is a function, so the real question must be 'what is sinx squared' or 'what is sin squared x': 'Sin(x) squared' would be sin(x^2), i.e. the 'x' is squared before performing the function sin. 'Sin squared x' would be sin^2(x) i.e. sin squared times sin squared: sin(x) x sin(x). This can also be written as (sinx)^2 but means exactly the same. Answer 2 Sine squared is sin^2(x). If the power was placed like this sin(x)^2, then the X is what is being squared. If it's sin^2(x) it's telling you they want sin(x) times sin(x).

Sin squared is equal to 1 - cos squared.
Sin squared, cos squared...you removed the x in the equation.
I suggest you use an online graphing calculator to do this. For example, you might try Wolfram Alpha.
no
sin squared
sin cubed + cos cubed (sin + cos)( sin squared - sin.cos + cos squared) (sin + cos)(1 + sin.cos)
No.
sin y is a function so the question does not appear to make any sense.
Note that an angle should always be specified - for example, 1 - cos square x. Due to the Pythagorean formula, this can be simplified as sin square x. Note that sin square x is a shortcut of (sin x) squared.
