The displacement of a particle is given by r(vector)=A(i^ coswt+j^ sinwt). The motion of the particle is:

a) an SHM

B) ON A straight line

c) on a circle

d) WITH CONTANT ACCELERATION

Dear Ramsing

r=A(i coswt+j sinwt)

x=Acoswt

y =Asinwt

square and add

x² +y² = (Acoswt)² +(Asinwt)²

x² +y² = (A)²

this the equation of circle
