Title: Term Test 2 Variant E problem 2
Post by: Kexin Wang on March 28, 2022, 03:25:10 PM
Hi, I just want to confirm with someone about the solution for Term test 2 variant E problem2. I think for$\lambda_n$ the n should start from 0, so n should be n = 0, 1, 2 and so on. I don't know if the solution makes a typo or am I missing some insights here.
