8 chapter ka 8.1 ka 5 questions |
| Answer» Sec A= h/b = 13/12. Let h= 13x and b=12x. Then p= √13x * 13x - 12x * 12x. = √169x² - 144x². = √25x². = 5x. 1. CosecA= h/p. =13x/5x. =13/5. 2. CotA =b/p. = 12x/5x. =12/5. 3. SinA = p/h. =5x/13x. =5/13. 4. CosA = b/h = 12x/13x = 12/13. 5. TanA = p/b = 5x/12x = 5/12 | |

Show that cube of any positive integer is of the form 9m, 9m+1, 9m+8, for some integer m |
| Answer» Let a be a positive integer and b = 3. Then r =0,1or2. Case first when r is equal to zero. a= ( 3q+0)² =9q² =3(3q²)=3m where m is equal to 3q². Case second when r is equal to 1. a= (3q+1)²= (3q)²+ 2*3q +1²= 9q²+6q+1 =3(3q²+2q)+1 = 3m+1. Where m is equal to 3q²+2q. Case 2nd when r is equal to 2. a= (3q+2)² = (3q)²+ 2*3q*2 +2² =9q²+12q+4 =9q²+12q+3+1 =3(3q²+12q+1)+1 =3m+1. Where m is equal to 3q²+12q+1 | |

Why pie is irrational number |
|
Answer» Bcoz the value of pie is assumed only i.e. 22/7 and it has a million of decimal places.?? Because value of π is 22/7 if we divide so not ending so it is non terminating vapue so it is irrational Because the value of π is 22/7 which gives non terminating non repeating value.So it is an irrational number. Because it has a different value at each step whenever we divide 22/7 at each rime we get a new value and the calculation never ends.... |
