In a layman's language definite integration is the number of boxes that a curve(function) covers on a particular axis(dx, dy, dz). Using the same method to solve it. We find that it covers 1 block from 1-2 and 2 blocks from 2-3(draw d graph to see it). So the answer is 3. You can use this at other places also.

xsiny + ycosx = 3

I'll write dy/dx as y'

Differentiating (Using Product Rule)

siny + xy'cosy + y'cosx - y sinx = 0

y'(x cosy + cos x) = y sinx - siny

y' = y sinx - siny / (x cosy + cos x)

gud 1 :)

It depends on your area of interest

R(Old) = [(rho) X l] / (pi) r^2

R(New) = [(rho) X 2l] / (pi) a^2 {a is the new radius}

Dividing the two We Get

R(old)/R(new) = a^2/2 r^2

In this case Volume is conserved so it can be used to relate r & a

(pi) r^2 l = (pi) a^2 2lr^2 = 2a^2

Substituting Above We get

R(old)/R(new) = 0.25

R(new) = 4 X R (old)

R(new) = 4 X 5

R(new) = 20

This is of the whole wire but as it is divided in two equal parts and resistance is directly proportional to length so the length of each piece will be 10 Ohm

Q = m Cp (t2 - t1)

Q = 1 X 4186 X (40 - 10)

Q = 125580 Joules

Power = Work Done / Time

836 = 125580/Time

Time = 150.2 Seconds

Hey guys dnt tk it personally actually d poem is vry specific dedicated 2 d parents of a fren of mine

The last Line is "I REALIZED HOW WRONG WAS I TO CONSIDER YOU THE BEST"

When I said buddy

You said study

When I did my best

You said I was below the rest

When I was unable to complete your demand

I felt being on a police remand

Even when I broke

You couldn't stop that poke

Bacuse when someone invited me to his nest

I realized was I wrong to consider you the best

Source - My anger towards some ever-demanding parents :)

Suggestions for the title are invited

I always wrote poems related to love but one fine day. I saw a play regarding gender disparity which gave rise to this poem. Hope you all will like it.

Why his words are treated as coming from a crown

And mine with an ugly frown

Why at every tough moment he gets your call

And I am deprived of it no matter how bad I fall

Why when he spends nobody comes to know

And when i do I become your foe

Why he so easily gets the required gadget

And in my case it's out of your budget

Why on his birthday loads of gifts galore

And on mine I get blessing and no more

Why did all the sacrifices I made

Feels as if hardly any difference did I make

Is that because you found me lying on the ground

Or you are ashamed to have me around

No matter how bad you treat

Shall never stop me from achieving my feat

So that my part of happiness comes towards me to embrace

And fulfills my desire to spit on your face

My creativity was moving on a cart

Till her eyes made it kick-start

It was just her presence which polished my art

This was her impact despite being miles apart

That she made my every sorrow depart

These reasons made her my sweetheart

As I started to treat her as my indispensible part

But when she said all I said was an aimless dart

All I am left with is a desire to show her my heart

Hope you all like it!!!!!!!!!!!

thnx

Nice one

Objective Mathematics by Pearson Education is good book for preparation as there is a very summarized to the point theory given and questions from all the engg entrances are combined in it and the quality of the questions is also good. Because the presentation of the book is better than other it gives you interest in reading it. The theory given is also a very good revision material for your 11/12th exams.

vry vry gud bt dude dnt tag it as academic
