let f(x) = ∫_0 ^1     (dt/(2+ch(xt)))  1) find a explicit form of f(x)  2) calculate g(x)=∫_0 ^1   ((tsh(xt))/((2+ch(xt))^2 ))dt  3) find the value of  ∫_0 ^1    (dt/(2+ch(3t))) and  ∫_0 ^1   ((tsh(3t))/((2+ch(3t))^2 ))dt  4) calculate u_n =∫_0 ^1     (dt/(2+ch(nt))) with n natural integr  and study the convergence  of the serie Σ (u_n /n) .
