dont know abt ur love story, but if you are really a mathematician, i have a problem for u ! a wegiht is attached to the end of a long spring in bouncing up and down ...as it bounces, its distance from the floor varies sinusoidally with time.. you start a stopwatch ..when the stopwatch reads 0.3 secs the wight first reaches a high point of 60 cm, above the floor..the next low point is at 40 cm..above the floor...occurs at every 1.8 sec.. now Predict the first POSITIVE value of time at which weight is 134 5/4 cm above the floor..(consider gravity too)
