  Integration from 0 to infinity x2cosx / (xsinx)2

3 years ago

Share

Answers : (2)

                                        

=x2cos(x)/(xsin(x))2


=x2cos(x)/x2sin(x)2


= cos(x)/sin2(x)


= cot(x)cosec(x)


Integrating it gives -cosec(x) 


Definite Integral frm 0 to infiniity is cosec(0)+cosec(infinity) ---> undefined

                                        integral x^2cosx/(xsinx)^2 dx
=integral cotx cosecx dx
=- cosecx +C

If each of the points (x1,4) , (-2,y1) lies on the line joining the points (2,-1),(5,-3) then the point P(x1,y1) lies on the lines ? Give the equation of that line.
 
 
equation of line joining (2,-1),(5,-3) is: 2x + 3y -1 = 0 Now (x1,4) , (-2,y1) lie on 2x + 3y -1 = 0. So it will satisfy. 2x 1 + 3*4 -1 = 0 and 2*-2 + 3y 1 -1 = 0 x 1 =-11/2 and y 1 = 5/3...

what is the value of sin 4530
 
 
Here we get some rotations of 360 +330 extra left. 4530%360=330 the 220 left will be effective angle as argument.... sin 330=-sin(360-330)=-1/2;
