Normal and simple difference is rational is terminating and non rational is non terminating

Raj Venkata 6 years, 1 month ago

Rational Number is defined as the number which can be written in a ratio of two integers. An irrational number is a number which cannot be expressed in a ratio of two integers. In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero. While an irrational number cannot be written in a fraction. The rational number includes numbers that are perfect squares like 9, 16, 25 and so on. On the other hand, an irrational number includes surds like 2, 3, 5, etc. The rational number includes only those decimals, which are finite and repeating. Conversely, irrational numbers include those numbers whose decimal expansion is infinite, non-repetitive and shows no pattern.

NCRET have we can obtained good marks by solving its all questions but RD sharma and other are aslo useful for that may might help us in fast processing and makes our ready to think hard.Due to solving additional our confidence level ups.But only maths doesnot make peecentage so take and study all subjects equall and make a daily routine for study subjects .All have equal value in board exam

Ankit Kumar 6 years, 1 month ago

If you study in goverment you revise ur ncert book and support material these two books helps u to good markss in board examination .if ur r not a student of govt. School.so use RD sharma

To find the value of tan 60 degrees geometrically, consider an equilateral triangle ABC since each of an angle in an equilateral triangle is 600. Therefore, ∠A = ∠B = ∠C = 60° Draw a perpendicular line AD from A to BC. Now consider the triangle, ABD and ADC, We have, ∠ ADB = ∠ADC= 90° and ∠ ABD = ∠ACD= 60° Therefore, AD=AD According to AAS Congruency, Δ ABD ≅ Δ ACD From this, we can say BD = DC Let us take, AB = BC =2a Then, BD= ½ (BC) =½ (2a) =a By using Pythagoras theorem, AB2 = AD2– BD2 AD2= AB2-BD2 AD2 =(2a)2 – a2 AD2 = 4a2-a2 AD2 = 3a2 Therefore, AD=a√3 Now in triangle ADB, Tan 600= AD/BD = a√3/a = √3 Therefore, tan 60 degrees exact value is given by, Tan 600=√3

Area of major segment = πr^2 - ( area of minor segment)

Area of minor segment =( πr^2 × thita)/360 - 1/2× r^2 × sin thita

its ok .... i can understand it???

Aadya Singh ? 6 years, 1 month ago

Sorry...sorry...it's not arc...it's area of minor and major sector

Aadya Singh ? 6 years, 1 month ago

Sorry, area of minor arc = (πr^2 × thita)/360 and area of major arc = πr^2 ( 1- thita/360)

Aadya Singh ? 6 years, 1 month ago

Area of major arc = (πr^2 × thita )/ 360

Aadya Singh ? 6 years, 1 month ago

Length of major arc = 2πr - (2πr × thita)/360°

Aadya Singh ? 6 years, 1 month ago

Length of minor arc =( 2πr× thita)/360°

Apurva Vaidya 6 years, 1 month ago

The length of AB is 12 cm. Step-by-step explanation: Given data: ∠ACB = ∠CDA AC = 6 cm AD = 3 cm To find: Length of AB From the figure attached below, in ∆ ABC & ∆ ACD, we have ∠A = ∠A ….. [∵ common angle for both the triangle] ∠ACB = ∠CDA ….. [∵ given] ∴ By AA similarity, ∆ABC ~ ∆ACD Since the sides of two similar triangles are proportional to each other ∴ \frac{AB}{AC} = \frac{AC}{AD} = \frac{BC}{CD} Now taking, \frac{AB}{AC} = \frac{AC}{AD} ⇒ AC² = AB * AD ⇒ 6² = AB * 3 …… [given AC = 6 cm & AD = 3 cm] ⇒ 36 = AB * 3 ⇒ AB = 36/3 = 12 cm
