To work out if a given point with coordinates (X,Y) falls on a line you must work out the equation for the line. All straight lines follow the formula: y=mx+c with 'y' being the Y coordinate, 'x' being th...

Use integration by parts

let u=ln(x)

let dv/dx=x

therefore du/dx=1/x and v=(1/2)x^2

therefore the integral of xln(x) is equal to the following:

(1/2)x^2ln(x) - (integral...

4x + 7 = 27 4x = 20 x = 5

36x^2 + 4

1. Take the third person plural of the verb in the preterite tense: Estar - estuvieron 

2. remove the 'on' - estuvier
