If we have to find out the truth value of a proposition and if it turns out to be sometimes false and sometimes true can we say it is multiple valued or should we say it cannot be determined?



UPD:What this question is whether the term 'truth value' is a single valued term or it is a multiple valued term . If it is a single valued term and for an boolean expression the TRUTH TABLE contains entries both true and false for the expression . Then should we say the TRUTH VALUE of the expression is multivalued or should we say it cannot be determined .



It's a question of post graduate entrance exam and the answer is "it cannot be determined " but I'm not getting the
the real logic behind the answer . Searched a lot and then only clue I was able to find out is may be they were trying to confuse over the term truth value.
So I m just asking what's the actual concept here is?

  • It just means its truth value is conditional on the truth values of the inputs. The proposition is neither a tautology (always true) nor a contradiction (always false).

A statement that is sometimes true and sometimes false is called a contingency: apparently, it's truth-value is dependent (contingent) on the actual state of affairs at hand.

I've noticed that in most equations given to represent a cone, there is no parameter which defines the tilt of the cone in 3D space and that most of them have their point at the origin $(0,0,0)$ - I was wondering if anyone could give me a more generalized cone equation for a cone in any position in 3D space 3d share | cite | improve this question edited Jul 25 '16 at 0:05 ervx 9,425 3 13 36 asked Jul 24 '16 at 15:38 Charlene 11 2 2 Welcome to Math.SE! Could you please explain a few things to help people give an answer useful to you: 1. What do you mean by "generalized tilt"? 2. Are you asking about a right circular cone? Does the angle at the vertex matter? 3. What form of answer (implicit, parametric...?) are you looking for? 4. If this is homework, what tools do you have available, an...

            Color the edges and diagonals of a regular polygon

            Clash Royale CLAN TAG #URR8PPP up vote 5 down vote favorite 1 Here is the problem: For what $n$ is it possible to color the edges and diagonals of an $n$-side regular polygon with $dfracbinomn23$ colors, such that you use every color exactly three times and for every color the three segments (edges or diagonals) with that color form a triangle? Trivially $nequiv 0 text or 1 pmod3$. I can also prove that if the statement is true for $k$ than it is true for $3k$ as well. How to finish? Please help!

            Relationship between determinant of matrix and determinant of adjoint?

            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite We are studying adjoints in class, and I was curious if there is a relationship between the determinant of matrix A, and the determinant of the adjoint of matrix A? I assume there would be a relationship because finding the adjoint requires creating a cofactor matrix and then transposing it. linear-algebra determinant adjoint-operators share | cite | improve this question asked Nov 17 '17 at 17:32 CluelessCoder 32 5 For a square matrix $A$ of order $n$, we have $A(operatornameadj A)=(operatornameadj A)A=|A|I_n$ where $I_n$ is the identity matrix of order $n$. This should tell you about the determinant of the adjoint in terms of that of $A$ (use multiplicative property and other elementary properties of determinants). – Prasun Biswas Nov 17 '17 at 17:35 1 @CluelessCoder: see here: math.stackexchange.com/questions/516127/…...
