Mr and Mrs Davis have a son. His name is Bobby, and it was his birthday a few days ago.
Last Sunday Bobby's grandfather came to visit them, and he brought Bobby a nice toy train. When he gave it to Bobby, he said: "I'm sorry, Bobby, but I forgot your birthday last Tuesday, so I give you this present then."
"Oh, that doesn't matter Grandpa," Bobby answered. "Thank you very much. It's just what I wanted."
"And how old are you now, Bobby?" his grandfather asked. Bobby knew the answer to that question. "I'm five, Grandpa," he said.
"That's good," the old man said. "You're a big boy now, Bobby. And what are you going to be when you're older?" Bobby knew the answer to that question, too. "I' m going to be six, Grandpa," he answered

есть формула кол-ва делителей
Пусть число a=(P1^K1)*...(Pn^Kn)
Тогда кол-во делителей b=(K1+1)*...(Kn+1)
То есть 32=2^5 => у него делителей 5+1=6
У 48 =3*2^4 у него (4+1)*(1+1)=10
у 5!=2^4*3^2*5 у него (4+1)*(2+1)*(1+1)=30
Cos(10+x)sinx>sin(10+x)cosx
cos(10+x)sinx-sin(10+x)cosx>0
sin(x-x-10)>0
sin(-10)>0
sin10<0
Верно, т.к. число 10 на числовой окружности находится в третьей четверти => sin10<0 => cos(10+x)sinx>sin(10+x)cosx
