    Is the Normal Spherical Image of a Curve Always Non-Constant?

    all functions anda curves considered here are assumed to be of class at least C3. If x(s) is a regular curve parametrized by arc length s, then t:(a,b)-> R3 defined a curve on S2.. this curve might not be regular and is called the tangent spherical image of x. the normal spherical image...

    How Can 1+1 Equal 0 in Certain Mathematical Contexts?

    helo.. We know that 1+1 = 2. but try this out..there is some dummy things goes around here Firstly, we denote 1 + 1 = 1 + \sqrt{1} <=> 1 + \sqrt{(-1)(-1)} <=> 1 + \sqrt{-1}\sqrt{-1} <=> 1 + i*i <=> 1 + (-1) <=> 0 ?? how come 1+1=0 ? and where is the...
