Advanced Calculus and Numerical questions (Maths)

I have attached some Maths questions involving calculus , numerical analysis and some Matlab. The numerical analysis relates to Gaussian, Gaussian-cote and taylor series with use of matlab in solving the problems. I would need solution in 24 hours thereabout. Please only bid after you have gone through the question and you know you can offer the solution within the short possible time. I would be online until the next few hours to pick the best bid. I have attached the questions.
