@silverinth Hi, it's good, but the last part i would say l'italia sembra essere un paese incredibile che voglio davvero visitare per conoscere meglio la lingua, la storia e la cultura.
@trishstudies The highest is where sin=1, so y=105+115=220;
for the distance of the peak 220=105sin(0.008x)+115, sin(0.008x)=1, 0.008x=π/2+πn, the first max is with n=0 so x=π/(2×0.008)
@kaedeC25H28N6O7 U have to see how the last digit behaves with exponentiation and how often it repeats, then u divide the exponent by the number of repetitions and see the remainder of the division.
3^1=3, 3^2=9, 3^3=7, 3^4=1, 3^5=3,...; 4 repetitions: 2020/4=505 rem=0; the last digit is 1
