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

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 (-).

Fun fact: The Rh factor is named after the Rhesus monkey, in which the protein was first discovered.

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...

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 ।।

Voices inside the head


It kills you from inside,

Haunts every night

Echoes inside the head

Like demons calling from hell.

Paint a smile

Of no joy

Keep moving

Thinking you will find what lacks behind.

Say, Hi! To your friends

Give them a smile

Yes, I’m proud of you, boy

Even it kills you from inside.

Your girlfriend left you at the edge

What a fucking disgrace!

Now you even can’t concentrate

Your study going down the drain.

R u thinking of expressing...
