10. The number of research articles in a prominent journal written by researchers during 1983-2003 can be approximated by ?(?) = 4.1?^0.6? /0.2+?^0.6? thousand articles per year (0 ≤ ? ≤ 20) where ?time in years is (? = 0 represents 1983). Assuming there were 0 articles prior to 1983, find an expression for the total number of articles (in thousands) written since 1983.
We will integrate the function U(t) from t=0 to t=20 to find the number of Articles published since 1983 till 2003.
