To answer your question, this could be the possible answer and i hope you understand and interpret it correctly:
<span>[Integrate [0, 1/2] xcos(pi*x
let u=x so that du=dx
and v=intgral cos (xpi)dx
v=(1/pi)sin(pi*x)
integration by parts
uv-itgral[0,1/2]vdu just plug ins
(1/pi)sinpi*x]-(1/pi)itgrlsin(pi*x)dx from 0 to 1/2
(1/pi)x sinpi*x - (1/pi)[-(1/pi) cos pi*x] from 0 to 1/2
=(1/2pi)+(1/pi^2)[cos pi*x/2-cos 0]
=1/2pi - 1/2pi^2
=(pi-2)/2pi^2 ans</span>
Answer:
259200
Step-by-step explanation:
so there are 86400 in one day. multiply by 3.
Answer:
Point slope:y - y1 = m(x -x1)y - y1 = m(x -x1)
Given values: (x1 , y1) = (2 , 3)m = 3
Solution: y - 3 = 3(x - 2
Step-by-step explanation:
hope this helps if not let me know have a good day
X^2 - 3x + 2x - 6 = 0;
x( x - 3 ) + 2( x - 3 ) = 0;
( x - 3 )( x + 2 ) = 0;
x - 3 = 0 or x + 2 = 0;
x = 3 or x = 2
The solution to the equation are 2 and 3.
