well just a bit tedious method but still for those you fell diffilculty in relative motion

not a perfect method .but just a try.

we know,

x={x}+[x]

putiing [x] from above as x-{x}, we get the given eqn as,

{x}=3+x-x3

we know 0<={x} <1

so  0<= 3+x-x3<1

by obsevation we see that x must be lying between (1,2)

so [x]=1

so x= 

is anything mentioned about the ropes? as light or inextensible?

mass of man=?

coz i dont get any logic then of defining the condition

l1²+l2²=a²+b² 

plzzz help..altleat give some hint...

find summation of

f(x)=1/(rootx)

x goes from 1 to 100 

thank u very much hsbhatt sir.

the one who answers gets 10 rates.

common someone answer? TRIGONOMETRY isnt that pakao!

common newtons, eulid and arybhattas ,help me out.. 

some more answers? 

no one has the gut s to solve this?  

common u all r not dumb yaar!

atleast give a try? 

prove:

(1/sinA)+(1/sinB)+(1/sinC)   2  , if A,B,C are angles of triangle.

ie.prove that 2rt3 is the minimum value of the above.

5 rates to one who answers.

note: if possible plz give an answer in which u prove the above ondependently.ie not using the "to prove" and utimately proving it something like > 0 ,thus true and hence above must be true.

is it sin²2a

THEN ony 30 will satisfy.well then we know

sin²2a=(2sinacosa)²

=4(sin²a(1-sin²a))

now put this in your eqn and u should get the ans. 

dy/dx can be either +1 or -1.

we know cos-1 (cosx)=x ,(pi+x),-x,(-pi-x) depending on the value of x.here we dont know anything about x.(more precisely alpha-x)

using basic trigo)we get y=cos-1(cos *(alpha-x)  or cos-1cos(x-alpha)=alpha -x ,x-alpha etc .etc as above.

here alpha= tan-1(3/2)

on diffrentating we get dy/dx=+1 or -1 (.: alpha is a constant) 

case2:

-1/2 kx2+mgx=0

mgx=1/2kx2

2mg/k=x

initially kx1=mg

.: x₁=mg/k

.: x=2x₁

plzzzzzzz someone ans.

why r goiitians becoming so lazy to answer academic qnts and r are all just answering all time pass type question? r goiitians only interested in aswering simple questions and getting more rates rather than helping others and sharing quality knowledge??

what is definition of a salt

why do AgNO3 and NaIO3 react although both are salts??

isnt it that two salts dont react? if not plz give examples.

rates assured.
