Yes. I assume you mean (x2 + y2) / (a2 + b2) = 1. Set all the variables to the same value - for example, all equal to one - and you have a valid solution.
It is x = 0.
X= plus or minus 1
It depends on what precisely the question is. One possible answer is that the quadratic expression has a value of 2 when x = 0.
'A' squared, plus 'B' squared, must equal 'C' squared, but only if the 'C' side is the hypotenuse (long side). A right (or left) triangle MUST have ONE 90-degree angle.
yes 1 + cot x^2 = csc x^2

Why don't you figure it out yourself
It is x = 0.
1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5
Yes. 'sin2x + cos2x = 1' is one of the most basic identities in trigonometry.
X= plus or minus 1
one squared equals one.
Neither, one liter is equal to 1 decimeter cubed.
