THESE ARE THE THEOREMS THAT WE DISCUSS HERE:

THEOREM_1.The angle that an arc of a circle subtends at the centre is double that which it subtends at any point on the remaining part of the circle.

THEOREM_2 Angles in the same segment of a circle are equal (without proof).

THEOREM_3.Angle in a semi-circle is a right

THEOREM_4.Opposite angles of a cyclic quadrilateral are supplementary.

THEOREM_5.The exterior angle of a cyclic quadrilateral is equal to the opposite interior angle (without proof)

Concentric circles : Two or more circles are said to be concentric if they have same centre and different radii. In the adjoining figure, 0 is the centre of each circle drawn; so the circles are called concentric circles. 2. Equal circles : Circles are said to be equal or congruent if they have equal radii. 3. Circumscribed circle : A circle that passes through all the vertices of a polygon is called the circumscribed circle. The centre of circumscribed circle is called circumcentre and the polygon is called incribed polygon. See below : 4. Inscribed circle : A circle that touches all the sides of a polygon is called the inscribed circle j(or, in-circle) of the polygon. The centre of inscribed circle is called incentre and the polygon is called circumscribed polygon. 5. Chord : The line segment, joining any two points on the circumference of the circle, is called a chord. A chord, which passes through the centre of the circle is called diameter, and is the largest chord of the circle. Arc and its types : An arc is a part of the circumference of a circle. A chord divides the circumference of a circle into two parts and each part is called an arc. In the figure, given alongside, chord AB divides the circumference into two unequal arcs APB and AQB. The arc APB, which is less than the semi-circle, is called minor arc and the arc AQB, which is greater than the semi-circle, is called major arc. Segment and relation between arcs and segments : A segment is the part of a circle bounded by an arc and a chord.

Why do mobile numbers in India have 10 digits ?

The answer, as expected, lies in Mathematics

Checkoutthisvideo

From 10 digit mobile numbers, we have 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 10,00,00,00,000 = 10 billion numbers at our disposal.

That is Permutations & Combinations Chapter at work

So what is Permutations & Combinations?

When the order doesn't matter, it is a Combination.

Which is a better resource to learn linear algebra, Gilbert Strang's lectures or the lectures from Khan Academy?

Originally Answered: What is a better resource to learn Linear Algebra, Gilbert Strang's lectures or from Khan Academy?

Go with Strang's lectures if you're good at math and Khan Academy if you want it explained like you're five. I listened to Strang's lectures after taking linear algebra and still learned a lot from them. But when I watched Khan Academy they took several minutes to explain really simple concepts and examples.
