very nice!!!!!!!!!!!!!!

one for galz here (b-1,g0)

d.c pandey is the besssssssssssssst how ever the new edition is not so good but previou one was great!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

this does not hold for n=1

isn't it

(sinx+cosecx)² +(cosx+secx)²=sin ²x+cos²x +2+2+cosec²x +sec²x

=5+(secxcosecx)²

for MINIMUM VALUE X=

/4

MINIMUM=5+(

2)²=9

what do you say

we have

1+n²+n³+...............+n⁵¹¹=(n⁵¹²-1)/(n-1)

=(n²⁵⁶-1)(n²⁵⁶+1)/(n-1)

now n-1 divides n²⁵⁶-1

hece k=256

it is used when there are 2 wavwes and you want to know the net efeective wavelength when they superpose upon each other

thi priciple can be used where you want to calculate tthe net force electrostatic experienced by a particle

S P can be used in situations where you want to know the net electrostatic force experienced by a particle.

please type the questions here?

from every point on the parabola itself three normals can be drawn.

may be right .but not for me
