i really need someone to solve this limit for me, cause im not sure if i did it right, it has to be done using taylor and young
lim senhx^3 - senx^3 /x^9
Not exactly, were supose to solve the limit using the usin taylor series and (resto de Young) which i dont know exactly how to translate into english, it would be like the rest of young which sounds dumb. But its basically the error o(x^n). Sorray i dont really know how to explain.
But basically the problem i have with the limit is the answer i dont understand why its one third, what happened to the factorial?
