1second one...
x=A+(B-A)cos2wt+C/2(sin2wt)
x=A+(B-A)/2(1+cos2wt) +C/2(sin2wt)
x=(A+B)/2 + (B-A)/2 (cos2wt) +C/2 (sin2wt)
now approach using options....
first is wrong......
second...rit !!!!!!!!
third wrong
fourth rit!!!!!!!!!!
hey dudes can anyone help me with a shms in different direction like in
r=(1+2coswt)i+(3sin^{}2 wt)+(3t)k
the qiestion asked was what is the shm and what is the time period and so on...........x=Asin^{}2 wt+Bcos^{}2 wt +Csinwtcoswt
this was a previous iit question if u all can remember
the choiches were
the equation represents shm for which of the folowing values
a) for any value of abc except c=0
b)a=-b and c=2b and amplitude is broot 2
c) a=b,c=0
d)a=b,c=2b amplitude is B
pls tell me how to appproach these sums
