i dont understand ur quesn

let me present mine its simpler point out d mistakes if ive committed

1stlycos^2 [2x] +cos^2[3x] =sin^2x

hence by trans4masions cos^2x + cos4x + cos2x =0

so cos2x[cos2x +cos4x] =0
hence d soln r 2x=(2n+1)/2 =>x=(2n+1)pie/4 & by d above equation

x=(2k+1)pie/6 & (2m+1)pie/2

a short cut 4 dis is 1st as it is mentioned ven |z| =1 lets take z=i

hence p(z)=c-1+ib hence |p(z)| =1

so b^2 +c^2 -2c =0 hence b^2+c(c-2) =0

since b^2 is non -ve so b=0 c=0 c=2 r d so.lution der

d ordocentre of a triangl is (2,1) & d circumcentr is [7/2,5/2] den d centroid is [wanted shortcut]

yuhoo hey guys its a tough quesn i got up2 a lt n den due 2 hevi calculasn i cudnt continue help me plz actually quesn is a^2 b^2

--------------------- + ----------------

rt[1+a^3][1+b^3] rt[1+b^3][1+c^3]

+ c^2

----------------- <=4/3

rt[1+a^3][1+c^3]

a small circular coil of radius r n no.of turns n is placed at d centre of anoder big circular coil of radius R n no.of turns N. initially d 2 coils r coplanar n d same current i flows thru both coils den d amount of work done in rotating d small coil about any of its diameter by an angle pie vil b ?

3 long wires of resistances in d ratio 3:4:5 r connected in parallel 2 each oder as shown if net force on middl wire is 0 den d1/d2 = ?

wat does d ? represent

a charged particle of mass m n charge q is accelerated through a potential difference of V volts it enters a region of uniform magnetic field which is directed perpendicular 2 d direction of motion of particle d particle will move on a circular path of radius given by ? ans: rt[2Vm/q] * [1/B]

a particle of debroglie wavelength 2.21 *10^[-13] n charge 1.6 *10^[-19]c is projected with a speed 2*10 [6] m/s at an angle 60 2 d x axis if a uniform magnetic field of 0.3T is applied along d yaxis d path of d particle is ans: a helix of radius 0.03m n time period 6.25 [pie] 10^[-8] sec

me 2 send me on ayshu@google.com plz

hey i dont understand d quesn n d ansr explain plz

good btetarbe brilliant job

hellllo pratik !!!!!!!!!!!!!!!!!!!!! yaar 23 is not an even no its actually an odd no so d coeff must be zeeeeeeeeeeeero

aree yaar its nothing but solving d given equations so as 2 get d relation btw a,b-c so dat v cud sub d obtnd values in it do u understand ? if s den rate me

={a{b^2+c^2-2bc] +b[c^2+a^2-2ac]+c[a^2+b^2-2ab] } /abc
=ab[a+b] +ac[a+c] +bc[b+c]/abc -[6]
=-3-6=-9
simpl yaar rate me
