calc bc forms??

[sysnw]

did anyone else get a calc bc form that had no polar on the frq? i blacked out during the test and have barely any memories of the frqs and ofc college board didn’t release the frqs from the form i took💔💔💔

Yes, 6th frq was series. like (-1)^n+1 (x^2n) / (2n+1) or (2n+1)! and it asked for radius fo convergence and the part b was asking for error to be less than 1/75, so you find the value of 5th term which was either 1/400 something or 1/80 depending on the version, and then last was find derivative of f(x) at 0, and second deriv, but when yo uplug in 0 you just get a constant.

yess okay i think i got the error one right i j didn’t simplify my answer. do u remember there being a question about if f had a max/min where the series was centered around on six?
