sin4x=(4sinxcosx)(1-2sin^2x)
Until an "equals" sign shows up somewhere in the expression, there's nothing to prove.
To prove the identity ( \tan^2 x - \sin^2(\tan^2 x) \sin^2 x = 0 ), we start with the definitions of tangent and sine. Recall that ( \tan^2 x = \frac{\sin^2 x}{\cos^2 x} ). By substituting this into the equation and simplifying using the Pythagorean identity, we can show that both sides of the equation are equal. Thus, the identity holds true for all ( x ) where the functions are defined.
It is believed that Einstein was the one who made up the equation yet there is much speculation surrounding it validity and many have tried to prove him wrong.
Cannot prove that 2 divided by 10 equals 2 because it is not true.
E=mc2 was correct, according to various sources. This theory represents that a small amount of matter can release a large amount of energy. An example to prove the answer to this question is a nuclear reaction, or explosion. This equation stands for Energy equals the mass of an object times the speed of light (299792458 m/s) squared (represented by c2). Because even a small mass times the spped of light squared is a unit of energy beyond imagining.

For any right angle triangle its hypotenuse when squared is equal to the sum of its squared sides.
No. A credit card does not prove age or identity.

You can't it equals 2. You can't it equals 2.

No you can not prove that 9 +10 = 21.
Yes. Identity, age and citizenship.
Multiply both sides by sin(1-cos) and you lose the denominators and get (sin squared) minus 1+cos times 1-cos. Then multiply out (i.e. expand) 1+cos times 1-cos, which will of course give the difference of two squares: 1 - (cos squared). (because the cross terms cancel out.) (This is diff of 2 squares because 1 is the square of 1.) And so you get (sin squared) - (1 - (cos squared)) = (sin squared) + (cos squared) - 1. Then from basic trig we know that (sin squared) + (cos squared) = 1, so this is 0.
