in aieee there is a scope of applyin shrtcuts

in many qustnz

can u ppl post "em if u knw

sourab_MCA

i know plenty of them, but only if u rate me , ill share that secret knowledge with u

guptaayu

arey ofcourse i ll rate u

but i dunno abt othz

when a glass slab is placed in front of a slit in a young double slit experiment, then the central maximum shifts towards that side which has slab

thr are plenty of shortcuts in maths
like for sum of n terms
put n=1 or 2
similarly in binomiall u can put desired value of r and n
in trigno angles can b put as u want them
like in conditional specially
get all a b and c as 60 degree
den in 2 d geometry too
thr are plentyyy of shorttricks
and whch comes trgh practice only
rmmbr one thing
ne result will hold for all values
so u can put ne value unless stated othrwise

ashish_banga

shortcuts 4 aieee

nitiagr

in physics many sums can be solved by dimensional analysis

guptaayu

plz refer a book 4 shortcuts

Anant.Dutta

you do not get good shortcuts in books.
u develop them with practice.

sourab_MCA

do u really want those secret short-cuts , then nudge me.

sorry gupta, i visited this topic lately. coz i was busy submitting my project work.

ne way, as a warm-up let me put this question here.and if ne 1 knows the short-cut for this then post here,otherwise ill give d short-cut.
i know many of u know d trick but those who dont know will benefit from it

what is the easiest way ne 1 of u can solve this

(2+3)(2w²+3w)(2w+3w²)

if all knows it then there is no need for me to post the solution(short-cut)

but remember this is just warm-up.more to come :)

sourab_MCA

c'mon no 1?

guptaayu

what is the need 4 ths(2+3)

cant u directly write 5

well whatz d shortcut

The time taken to double and triple the thickness of ice will be in the ratio of
t1 : t2 : t3 = 12 :22 :32

the time for thickness of ice grpwing from x1 to x2 is given by
t = L [x22 -x12 ]/ 2K
L- latent heat of ice
- density of ice
K- conductivity

when n number of particles are located at the vertices of a regular polygon of n side having side length a and if they start moving heading to each other
they must collide at the centrre of the polygon after the time

t = a / { v [ 1-cos2/n ] }

v- speed of each particles
