A particle is moving around the unit circle (the circle of radius 1 centered at the origin). At the point (.6, .8) the particle has horizontal velocity dx/dt = 3. what is its vertical velocity dy /dt at that point?

the sin of the angle between horizontal and the resultant tangent at (.6,.8) is dy/dt/3 = -3/5

so dy/dt = -9/5
