dy/dt = y+6t y(0)=5. In this question we will use a spreadsheet to approximate the value y(1). The picture below shows a spreadsheet being used to implement a linear approximation scheme (ie. Euler's method) with initial value y0= y(0)= 5 and a step size of 0.1 to make such an approximation in 10 steps. A downwards arrow indicates that the contents from the cell above will be dragged down. Column B holds values of t; Column A holds approximations of y(t); and Column C holds approximations of y'(t).
