Varun u wont get solutions unless u rate them

kbanagar slope of xt graph is VELOCITY
Shinee ur approach in analogy with velocity i only approximately correct though it gets the ans within the options
Here you can solve it usin integration
dA/dt = .5 is rate of change of acc
acc at any time is 2 - .5 t
vel at any time is 2t - .25t^2
dist travelled is t^2 - (t^3 /12)
when t is 4 dist is 32/3
I hope you agree????

Ans on fluid mechanics
jus kidding !!!! ?????
|

Formula for rot of axes is
X= (xcosO - ysinO)
Y= (xsinO + ycosO)
If eq of line is sometin else apply the shift in axes as X+ h and Y +k
|
|
|
|
|
1 rt (x/2 + 1) + rt(x/2)
2 4.1 ( It is sol to 9X^3 - 125 X = 108 )
3 What is - -
|
|
|
|
tk+1 = nCk X^n-k * ( 1-X)^k
diffrentiate to obtain maxima
|
|
|
|
|
|
It is 10P8 *(10C2* 8C2 + 10C3 ) = 2503872000

I tink ur ques is wrong
why is it 3^1-sin2x+2sin2x wen it can be 3^1+sin2x
|
|
|
|
0* infinity = -1
multiply both sides by 0
0=0
therfore -1 is correct ans !!!!!!
please dont play with maths
|
|
|
|
X= (x -y) cosO
Y= (x + y)sinO in new convention
here O= 45*
|

nuksi
this is concerned with rotation of axes
|
|
|
|
|
the ans is none of these it may be hyperbola if R1-R2> 0 and straight line if R1=R2
|
|
|
|
ans is 15\(29^2)
partially differentiate mirror eq to get ans
|
|
|
|
|
hey allam another mistake u mad is that X=(x-y)\root 2 and same for Y also . hence const term is 2
|
|
|
|
|
Well man for that there is no need to express it as pi+ something.
Why the confusion when ans comes in single step
