let f(x) = ∫_0 ^1 (dt/(x +ch(t)))
1) find a explicite form of f(x)
2) calculate ∫_0 ^1 (dt/((x+ch(t))^2 ))
3) find the value of ∫_0 ^1 (dt/(1+ch(t))) and ∫_0 ^1 (dt/(2+ch(t)))
4) find the value of ∫_0 ^1 (dt/((1+cht)^2 )) and ∫_0 ^1 (dt/((2+cht)^2 ))
a boy is in front of a wall.The distance between
boy and wall is 12ft.the boy is moving towards
the wall in such a way that half the distance
between the wall and him is crossed in one
minutes.So find the time the boy reach to the wall
