what the fuck is double sigma notationdo I need to know how to prove double sigma notation and also if I do how do I learn it cuz my teacher won't teach it
It's when u express smn like (1+x)^3*(1+3)^8 and u can make a double sigma notation out of it bc two brakcet thingos . its not that hard tbh but very time consuming and not worth the hassle as not in syllabus iirc.what the fuck is double sigma notation
if you wanna get a single term like x^4 it seems way faster to just find certain coefficients from (1+x)^3 and multiply by the other coefficients from (1+3x)^8 or smthIt's when u express smn like (1+x)^3*(1+3)^8 and u can make a double sigma notation out of it bc two brakcet thingos . its not that hard tbh but very time consuming and not worth the hassle as not in syllabus iirc.
U tell me man idk how to prove thiswhat the fuck is double sigma notation
write it out and group it a bitU tell me man idk how to prove this
not in syllabusU tell me man idk how to prove this
