m = E/c^2
In number Systems , the opposite of the number can be represented by changing and reversing the sign of the number.-2 is the number is the opposite of the number 2.
A number's opposite is the negitave of that number... the opposite of 2 is -2, the opposite of 947283 is -947283.
The additive opposite is +1/2. The multiplicative opposite is -2.
A negative number. For example: -I -2 I = -2 because -2= 2 and the opposite of 2 is -2.
A parallelogram has 2 equal opposite acute angles and 2 equal opposite obtuse angles.
2 opposite acute angles and 2 opposite obtuse angles with opposite parallel sides
-2 -2

A rhombus has 2 opposite acute angles and 2 opposite obtuse angles
If you mean the complex number √-2, then: hopefully someone else can answer (sorry). If not, then sin(arc cos((√2)/2)) = (√2)/2 Cosine is the ratio of adjacent/hypotenuse. Using Pythagoras the third side, opposite the angle, can be found: 2² = opposite² + (√2)² → 4 = opposite² + 2 → opposite² = 2 → opposite = √2 Then: θ = arc cos((√2)/2) → cos θ = (√2)/2 → sin θ = (√2)/2
The answer depends on whether you want the additive or multiplicative opposite. Additive opposite = +0.5 Multiplicative opposite = -2.
