Answered a Question in Math
Given `int x^2/sqrt(36x^2) dx` This can be solved by using the Trigonometric substitutions (Trig substitutions) when the integral contains `sqrt(abx^2)` then we have to take `x=sqrt(a/b) sin(t)`...

Given , `int sqrt(1x^2)/x^4 dx` By applying Integration by parts we can solve the given integral so, let `u= sqrt(1x^2)` `,v' = (1/x^4) ` =>` u' = (sqrt(1x^2) )'` => =`d/dx (sqrt(1x^2))...

Given , `int sqrt(164x^2)dx` This Integral can be solved by using the Trigonometric substitutions (Trig substitutions) For `sqrt(abx^2)` we have to take `x=` `sqrt(a/b) sin(u)` so here , For... 
Answered a Question in Math
Given, `int sqrt(1x)/sqrt(x) dx` let us consider `u= sqrt(x)` , we can write it as `u^2 = x` Differentiating on both sides we get => `(2u)du = dx` Now let us solve the integral , `int...
