I still not getting how even start to answer a question related to Taylor Polynomials so please I need some strong help and advice in how to tackle such questions as this ones above:
i) Use Taylor polynomials p1,p3,p5,... about 0, successively, to evaluate sin(pi/10) to four decimal place showing all your working.
ii) Use multiplication of Taylor series to find the quartic Taylor polynomial about 0 for the function f(x) = e^x - 1 / sqr of 1+x
evaluating the coefficients
I don't need just an answer I also need I follow trough with explanations of what is happening.
