1)Given that the force of interest is = .05 + .006t, find the accumulated value after three years of an investment of 300$ made at time 0 and then at time 4.
For this one, I thought I would integrate the force of interest function to get the accumulated function, but I am not getting the right answer. Not sure what I am doing wrong.
