What is the difference between axioms and postulates? give me correct answer plxxxx |
|
Answer» AXIOMS and Postulates. A statement, usually considered to be true without proof (that is, something which is self-evident) is said to be an axiom. ... A postulate can be specific on a particular field while an axiom generally is true for any field in SCIENCE. Sometimes non-logical axioms are referred to as postulates.

Show that 2-root3 is irrational no |
|
Answer» prove that 2+ √3 is IRRATIONAL.
Let us assume, that 2 + √3 is rational. Then, There EXIST CO - primes a and b (b≠ 0) So, ➝ (2 + √3) = a/b
But , we know that √3 is irrational. So, this contradiction is arissen because of our wrong assumption. Hence, (2 + √3 ) is irrational. ━━━━━━━━━━━━━━━━━━━━━━━━━ |

Define axioms and postulates?answer me guys |
|
Answer» hlo listen...give me 30thanks i will give you...70thanks. BEST offer let's do it.. okay An axiom or POSTULATE is a statement that is taken to be true, to serve as a premise or starting point for further reasoning and arguments. The word comes from the Greek axíōma (ἀξίωμα) 'that which is thought worthy or fit' or 'that which commends itself as evident.'[1][2] An axiom or postulate is a statement that is taken to be true, to serve as a premise or starting point for further reasoning and arguments. The word comes from the Greek axíōma (ἀξίωμα) 'that which is thought worthy or fit' or 'that which commends itself as evident.'[1][2]The term has subtle differences in definition when used in the context of different fields of study. As defined in classic philosophy, an axiom is a statement that is so evident or well-established, that it is accepted without controversy or question.[3] As used in modern logic, an axiom is a premise or starting point for reasoning.[4] An axiom or postulate is a statement that is taken to be true, to serve as a premise or starting point for further reasoning and arguments. The word comes from the Greek axíōma (ἀξίωμα) 'that which is thought worthy or fit' or 'that which commends itself as evident.'[1][2]The term has subtle differences in definition when used in the context of different fields of study. As defined in classic philosophy, an axiom is a statement that is so evident or well-established, that it is accepted without controversy or question.[3] As used in modern logic, an axiom is a premise or starting point for reasoning.[4]As used in mathematics, the term axiom is used in two related but distinguishable senses: "logical axioms" and "non-logical axioms". Logical axioms are usually statements that are taken to be true within the system of logic they define and are often shown in symbolic form (e.g., (A and B) implies A), while non-logical axioms (e.g., a + b = b + a) are actually substantive assertions about the elements of the domain of a specific mathematical theory (such as arithmetic).

In most cases, a non-logical axiom is simply a formal logical expression used in deduction to build a mathematical theory, and might or might not be self-evident in nature (e.g., parallel postulate in Euclidean geometry).[5] To axiomatize a system of knowledge is to show that its claims can be derived from a small, well-understood set of sentences (the axioms), and there may be multiple ways to axiomatize a given mathematical domain. |

A park, in the shape of a quadrilateral ABCD has ∠C=90⁰, AB = 4.8 m,BC = 8√2 m, CD = 5 m and AD = 2√2 m. how much area does it occupy ? |
|
Answer» Answer: To FIND the area of a quadrilateral we divide the quadrilateral into 2 triangular parts and use HERON’s formula or any other suitable formula to calculate the area of the triangular parts. ____________________________ Solution: Given a quadrilateral ABCD in which ∠C = 90º, AB = 9 m, BC = 12 m, CD = 5 m & AD = 8 m. Join the diagonal BD which divides quadrilateral ABCD in two triangles i.e ∆BCD & ∆ABD. In ΔBCD, By applying Pythagoras Theorem BD²=BC² +CD² BD²= 12²+ 5²= 144+25 BD²= 169 BD = √169= 13m ∆BCD is a right angled triangle. Area of ΔBCD = 1/2 ×base× height =1/2× 5 × 12= 30 m² For ∆ABD, Let a= 9m, b= 8m, c=13m Now, Semi perimeter of ΔABD,(s) = (a+b+c) /2 s=(8 + 9 + 13)/2 m = 30/2 m = 15 m s = 15m Using heron’s formula, Area of ΔABD = √s (s-a) (s-b) (s-c) = √15(15 – 9) (15 – 9) (15 – 13) = √15 × 6 × 7× 2 =√5×3×3×2×7×2 =3×2√35 = 6√35= 6× 5.92 [ √6= 5.92..] = 35.52m² (approx) Area of quadrilateral ABCD = Area of ΔBCD + Area of ΔABD = 30+ 35.5= 65.5 m² Hence, area of the park is 65.5m² ================================ Hope this will help you... |
