Homework Statement
Question 1 :Find the value of [tex]\int^{\infty}_{0}[/tex][tex]\stackrel{dx}{a^{2} + x^{2}}[/tex]
Question 2 : Find the number of positive integral solutions of the equation :
[tex]x_{1}[/tex][tex]x_{2}[/tex][tex]x_{3}[/tex][tex]x_{4}[/tex][tex]x_{5}[/tex] = 1050
Homework Equations
Well I do not know any relevant equations.
The Attempt at a Solution
Well I tried the first question by substituting x with a(tan(y)) then I got sec[tex]^{12}[/tex] but then I don't know what to do. The second question has me stumped totally. I tried finding the factors of 1050 and then finding the permutations of the factors to get the answer but did not get it .
