If co-ordinates ofa moving point at time t are given by x=a (l+sint) a

1.	If co-ordinates ofa moving point at time t are given by x=a (l+sint) and y=a(1-cost), then:
Answer» the slope of accelration time GRAPH is zero the slope of velocity-time graph is constnat the direction of motion MAKES an angle t/2 with X-axis all of the above Solution :`(dx)/(dt)=a(1+cos t),(dy)/(dt)=SINT` `v=sqrt(((dx)/(dt))^(2)+((dy)/(dt))^(2))` `a=sqrt(((d^(2)x)/(dt^(2)))^(2)+((d^(2)y)/(dt^(2)))^(2))`
