phi Group TitleBest ResponseYou've already chosen the best response.1
This does not do the input. But it does give an idea a=pi/3, n=4; str2=''; for ii=0:(n1) switch mod(ii,4) case 0, ff= sin(a); case 1, ff= cos(a); case 2, ff= sin(a); case 3, ff= cos(a); end; if (ff<0) sg= '' else sg= '+'; end; if ii>0 str= sprintf('%2s %7.5f(x%2.4f)^%d',sg, abs(ff)/factorial(ii),a,ii); else str= sprintf('%7.5f',ff); end; str2= [str2 str]; end; str2

phi Group TitleBest ResponseYou've already chosen the best response.1
its output str2 = 0.86603 + 0.50000(x1.0472)^1  0.43301(x1.0472)^2  0.08333(x1.0472)^3

I really hate matlab for string manipulation clc syms x center = input('Enter the center of expansion: '); for i=1:3 disp( [subs(diff(sin(x), i), x, center), strcat('(x', num2str(center), ')^', num2str(i))]); end

I got this nasty code ... looks pretty close clc syms x center = input('Enter the center of expansion: '); to_out = ''; for i=1:10 to_out = strcat(to_out, '+' , strcat(char(subs(diff(sin(x), i), x, center)), strcat('(x', num2str(center), ')^', num2str(i)))); end disp(to_out);

the out put is ...for r=4 ... maybe tweak a little. +cos(3)(x3)^1+sin(3)(x3)^2+cos(3)(x3)^3+sin(3)(x3)^4
