The Rh factor(the Rhesus factor or Rh antigen), is a protein that can be found on the surface of red blood cells. It is one of the most important blood group systems in human blood typing. The presence or absence of the Rh factor is denoted as either Rh-positive (+) or Rh-negative (-).

निराशा

जीवनमा पलाएका ती नौलो आशाहरू,
पूरा हुन नपाई बिलाई सकेछ ।
याँहा को छर आफनो भनेर बोलाउ,
आफनो भनने सबै पराई भई सकेछ ।
हृदयमा फुलेका ती परितका फुल,
तिमरो माया नपाई आोईलि दिएछ ।
फकरिन लागेको आशाको दियो पनि
निराशाको भावमा खाग बनी खरानी भएछ ।।

Using bisection method, find the root of the equation f(x)=x² -6logx-3=0(2<=x<=3)'correct to 4 decimal places with an accuracy of 10^-2 .

Here, f(x)=x² -6 logx-3=0

f(2)=4-6 log2-3=-0.806

f(3)=9-6 log3-3=3.1373

f(2).f(3)=-0.806*3.1373=-2.529422 which is negative.

Hence, the root lies between 2 and 3

c₀ =(2+3)/2=2.5

f(2.5)=6.25-6 log 2.5-3=0.8623

Now

n	a(-ve)	b(+ve)	c_n	f(c_n)
0	2	3	2.5	0.8623
1	2	2.5	2.25	-0.050595
2	2.25	2.5	2.375	0.38664
3	2.25	2.375	2.3125	0.1631658
4	2.25	2.3125	2.28125	0.05506
5	2.25	2.28125	2.265625	0.001925

From the table,

f(2.265625)=0.001928<10^-2

Therefore, the...

Here, f: A—>B

f(x)= (x-1)/(x+2) ; x -2

A= {-1,0,1,2,3,4}

B= {-2,1,-1/2,0,1/2,1/4,2/5}

Range = {-2,-1/2,0,1/4,1/2,2/5}

As range is not equal to codomain so the given function is not bijective.

We can make it bijective by omitting {1} from set B

There are different ways to visualize infinity to ponder upon. This is some random thing about infinity in my head which I'll be mentioning.

Imagine any number, Keep on adding a certain value to it, Since we are talking big here, there is no limit to how much you add.

Keep on adding, Imagine that the progress of increment is like a progress bar. So, Is the progress bar really progressing? Since it doesnt really have an end and no...
