Take lcm of 770 and find the multiples.then u can find the positive integers
n=0 1 put n=1 1+2=3 n=2 8+4=12 n=3 27+8=35 …... so the smallest number is 1
X+Y=-b/a XY=c/a from 2 nd equation ax2-bx2+b+cx2+c-2cx (a-b+c)x2-2cx+b=0 alpha and beta are 2 roots alpha+beta=2c/(a-b+c) alpha*beta=b/(a-b+c) put X+Y and X*Y in this
THE NATURAL NUMBERSare the counting numbers: 1, 2, 3, 4, etc.Mathematical inductionis a technique for proving a statement -- a theorem, or a formula -- that is asserted abouteverynatural number. By...
root1=p root2=q pq=(-a-3)/8 p+q=6/8 p^2=q

Take a=3 e=3 f=6 g=1 or 2 b=any whole number bw 0 to 10 c=any whole numberbw 0 to 10 d=any whole numberbw 0 to 10
Hint: Find out the all the roots from the different factors. Mark them all on the number line. Then just check weather a perticular range between two roots satisfy the given inequality or not. Thanks.
Yes, its a good one, preferred book for IIT JEE. Check the link for recommended books http://www.askiitians.com/iit-jee/advanced/important-books.html
Question seems to have mistake. Please check it.
Hint:- You can directly verify the options by substituting the values in place of x.
use the formula 1/2{(w/2)*root(-1+w2)}+{(w/2)*root(w4+w2/2)}
Funtions in maths are generally formed using algebric equations and therefore then are coverd in algebra. Further composite functions are important in terms of higher mathematics where the practical...
Hint: Consider the 5 numbers be a/r 2, a/r, a, ar, ar 2 and try to simplify it. Thanks.
Dear Student, Mutually Exclusive events will be shown by non intersecting area in the Veen diagrams. Whereas, For independent events they may or may not intersect each other but they follow that P(AB)...
Hint: (b + ia )5 = i(a – ib) 5 = i(a+i(-b)) 5 = i(x-iy) = y+ix.
Hint: alpha + beta = -p, alpha*beta = -q. gamma + delta = -p and gamma*delta = r. Simply the given equation and replace the values with the above given values. Thanks.
Dear Student, Assume the speed of A is Sa and that of B is Sb. Consider the distance between the two is x and let y be the distance from B to their meeting point. Now make two equations based on...
This will be equal to selecting 3 out of 6 and then rearranging them for the different places ( 6 P 3 ). Thanks.
HInt.:Replace the values of f(x) in the RHS with the given value of it. Thanks.
aren’t the first and second optins are same? whatever it may be the correct ans is -1/2(a 2 +b 2 ) on solving the given equation into the form ax 2 +bx+c=0 we get x 2 +x(a+b+2c)+ab-(a+b)c=0 given the ...
first find the nth term of the series 1,3,5,7,........are in first place …........nth term=1+(n-1)2=2n-1 nth term=a+(n-1)d 3,5,7,9.........are in second place.........nth term=3+(n-1)2=2n+1 similarly ...
which paper are you talking of...??
Logarithm is not a big as well as the tough topic. Regarding theory you can refer any maths book of 11 th standard. Focus on solving different types of questions based on it. Thanks.
You can follow S L Loney Trigonometry andCoordinate Geometry books as are very good The best part of S L Loney Trigonometry is its coverage inHeights and DistancesandInverse Trigonometric Functions....
