C++ Euler's method is a numerical method for generating a table of values (xi , yi) that approximate the solution of the differential equation y' = f(x,y) with boundary condition y(xo) = yo. The first entry in the table is the starting point (xo , yo.). Given the entry (xi , yi ), then entry (xi+1 , yi+1) is obtained using the formula xi+1 = xi + x and yi+1 = yi + xf(xi , yi ). Where h is...

6. A common problem of mathematical physics is that of solving the Fredhol integral equation f(x)-ф(x) +1 K(x,t)ф(t)dt, where the functions f (x) and K(x, t) are given and the problem is to obtain ф(x). (a) Describe a numerical method for solving this equation. (b) Solve the...
TASK 4 2 MARKS L06J] One numerical method for calculating the cubic root of a number VX is by using iterations. The process starts by choosing a value xi as a first estimate of the solution. Using this value, a second a more accurate value x2 can be calculated wx22x) /3, which is then used for calculating a third, and more accurate value x3, and so on. The general equation for calculating the value of xfrom x is Xi+1 -...
