If X Occurs In The Expansion
expansionBy binomial theorem a b n k 0 n n C k a n-k b k Here a x 2 and b 1 x. The method is to find when the general term of the expansion corresponds to the power of x were looking for.

Let and suppose three numbers are chosen at random from the numbers 123m.
If x occurs in the expansion. It is straightforward to identify the terms where latexnlatex is an integer with a low value. If the coefficient of second third and fourth terms in the expansion of 1 x2 are in AP then show that 2n2 9n 7 0. The minimum pressure and tmeperature in the cycle are 100 kPa 25 C the compression ratio is 11 and the maximum temperature in the cycle is 1000 C.
Such a process occurs during the compression and power strokes for an internal combustion engine. In the first step 0L is the initial volume because the human lung goes from 0L of expansion to 050L of expansion when breathing. Atoms and molecules in a solid for instance constantly oscillate around its equilibrium point.
Analyze each of the four processes in this cycle for work and heat transfer and determine the overall perfomance of the engine. If xr occurs in the expansion of x 1x n then its coefficient is A nr2 B nr 1. Thermal expansion is large for gases and relatively small but not negligible for liquids and solids.
The method is explained with tutorials with detailed examples and practiced with exericses answer keys and worksheets. 2 n p 3. If in the Expansion of X 4 1 X 3 15 X 17 Occurs in Rth Term Then A R 10 B R 11 C R 12 D R 13.
Asked Feb 19 2018 in Class XI Maths by vijay Premium 539 points. On this slide we derive two important equations which relate the pressure temperature and volume which a gas occupies during reversible compression or expansion. If the coefficient of second third and fourth terms in the expansion of 1 x2 are in AP then show that 2n2 9n 7 0.
NIf the coefficient of the middle term in the expansion of 1 x 2 is p and the coefficients of middle terms in the expansion of 1 x2n 1 are q and r then a p q r b p r q c p q r d p q r 0. If m2n fro some then the chosen numbers are in A. If m2n1 then the chosen numbers are in AP.
There may be instances when we want to identify a certain term in the expansion of latexdisplaystyle xy n latex. Although it was not given in the problem it must be assumed. If x2k occurs in the expansion ofx1x2n-3 then A n - 2k is a multiple 2 B n - 2k is a multiple of 3 C kr 0 D none of these.
Prove that the coefficient of x p in the expansion of x 2 1 x 2 n is 2 n. -050 Latm x 101325 JLatm work -51 Joules. X xlog10 x if the third term in the expansion is 1000000 Roorkee 1992 a 10 b 11 c 12 d None of these 6.
Also we have 2 n in place of n. If x4 occurs in the rth term in the expansion of leftx4dfrac1x3right15 then r. Click hereto get an answer to your question If x p occurs in the expansion of x 2 1x 2 n.
Linear thermal expansion is ΔL αLΔT where ΔL is the change in length L ΔT is the change in temperature and α is the coefficient of linear expansion which varies slightly with temperature. Asked Feb 19 2018 in Class XI Maths by vijay Premium 539 points. You might multiply each binomial out to identify the coefficients or you might use Pascals triangle.
An example of this is the buckling of railroad track as seen in. Thermal expansion is the tendency of matter to change in volume in response to a change in temperature. We learn how to find a specific power of x or a specific term inside a binomial expansion without writing all of the terms in the expansion.
I assume the question as. Then prove that its coefficient is 2n. 1297 Consider an ideal air-standard Stirling cycle with an idealregenerator.
