the difference between the number of sides of a heptagon and the number of sides of a triangle is equal to .

The difference between the number of sides of a heptagon and the number of sides of a triangle is equal to __________. => The number of sides of a pentagon or The number of sides ..

>The absolute values of z 1 , z 2 and z 1 + z 2 are geometrically given by We know that the sum of any two sides of a triangle is greater than the third. Hence, in D ORP, we have with the equality holding only when O, P, Q are lying in a straight line. That is why this..

Given a, b, c and d are non-zero real numbers, we can deduce other proportions by simple Algebra. These results are often referred by the names mentioned along each of the properties obtained. (1) If then bc = ad This property is known as INVERTENDO. (2) If , then ad = bc This property is..

Prove that the statement P(1) holds good by putting n = 1 on one side of the statement and then simplifying it to take the form of the expression on the other side..

Let z= x + iy be a complex number. Taking log on both sides..

If a:b=c:d then a-b:b=c-d:d Subtracting 1 from both sides, we get ..

The general form of the trinomial is (x 2 + cx + d) where c and d have different numerical values: c = a + b, and d = ab. In these examples, study the relation between the middle and the last terms. Therefore, to factorise expressions of the type (x 2 + cx + d), we have to find two ..

When 'n' is a fraction. where 'p' is any positive integer and 'q' is any integer. From Part I, Now taking q t h root of both sides, Hence the theor..

By componendo and dividendo, we get Squaring both sides, By componendo and dividendo, we get x(b 2 +1)=2ab ..

A recurring decimal is denoted by placing dots or a bar over recurring digits. Express the following recurring decimals as equivalent fractions: (a) (b) (c) (a) Let x = 0.4444 Multiply both sides by 10 ( one digit is recurring)..
