Answer 1

The given questions revolve around complex analysis and differential equations, more precisely arguments of complex numbers and the concept of ordinary points in differential equations. However, Arg(1-1) or Argument of 0 may typically be undefined, hence might not hold as a universally valid statement. The statement concerning the ordinary points in nth-order D.E is not clear and the truth value can't be determined without proper context.

Step-by-step explanation:

The question seems to be based on Complex Analysis and Differential Equations. For starters, Arg is a function that denotes the angle (or argument) of a complex number, usually represented in the form of a+bi.

For the statement a, Arg(1-1) called the argument is not typically defined for the origin (0,0) in the complex plane but some may define it as 0. So, this might not be a universally valid statement. While for Arg(1+i), the value is π/4 or 45 degrees.

For the statement b, the wording is a bit unclear, but it seems to relate to the ordinary points of an nth-order differential equation (D.E). The ordinary point for a differential equation is where the coefficients of the differential equation are analytic, that is, cleanly differentiable. However, without the full context of the statement, it's difficult to accurately decide if it's true or false.
