static equi. is that one in which when equilibrium is achieved then the reaction comes to a halt unlike dynamic equilibrium where reaction still goes on.

for eg:-suppose 2 bodies of equal weight are kept on a see- saw thenwhen it comes just at equilibrium i.e in the middle then it moves to neither of the directions

 

Bingo!!!

i=^{[ ]}-1

 

i= (-1)^1/2

 

i⁰ = (-1)^(1/2*0)

 

therefore

 

i⁰= (-1)⁰

 

i⁰=1

 

 

Bingo!!!!!!!

 

Yes aatish

 

Multiplying & dividing the function by root2

the function modifies to

 

f(t)= ^{[ ]}2[ 1/^{[ ]}2 sint + 1/^{[ ]}2 cost]

    = 2 [ cos (pi/4) sint + sin(pi/4) cost  ]

 

ie =2 sin (pi/4+t) 

 

As this is single harmonic function therefore it represents SHM

 

 

Bingo...........
