i am just wondering how to input a command so that maple will display the O(x^6) and maybe a few other terms, so i can confirm my calculations

thank you very much every one for your time and input and especially your help robert wait what is that before the O(x^6) is an 'O' or zero is it a constant? anyway to make it display the constant?

oh sorry i was being not specific enough i mean solve for a general solution involving the sine integral for example if a question had y'' + [2 Si(x)y']/x^2 + [2 tan (x)y]/x^3 = 0 is there a function to get that into a series so i can solve it ? or is there such a command to give me a general solution
