Q2 An electrical device was measured for its current, 1 fluctuates at a number of different values of time, t. The results are given in the table below. Calculate the current, I at t = 1.4 second by using the following methods: t(s) 0.6 1.1 1.5 1.9 1(A) -0.6214 0.7114 1.9110 6.21 (a) The Lagrange interpolation with Linear and Quadratic approximation. (b) Newton's divided difference.
