Consider the points A(0, 0, 0), B(2, 0, ...

Consider the points A(0, 0, 0), B(2, 0, 0), `C(1, sqrt(3), 0)` and `D(1, 1/sqrt(3), (2sqrt(2))/sqrt(3))`
Statement - I : ABCD is a square.
Statement - II : `|AB|=|BC|=|CD|=|DA|`.

Satement -I is True, Statement -II is True, Statement -II is a correct explanation for Statement -I

If f(x) = sqrt(1-sqrt1-x^2 , then at x = 0

f(x) is differentiable as well as continuous

f(x) is differentiable but not continuous

f(x) is continuous but not differentiable

f(x) is neither continuous nor differentiable
