Evaluate ∫y0ksin(kx−π)dx where y and k are independent of x, and y is given by the solution to the equation cos(ky)=0.57 .
Given:
Jk sin (kx-x Where y and k are independent of x
To evaluate the ...
I = [ksin (kx-)dx = ksin(kx-)dx cos (kx-) = k k cos (k- = -cos(ky-)cos(k(0)-z) =-cos(ky-)cos (-) Use the following identity cos(-x)cos (x) (cos(ky) cos(7)+ sin (ky)sin ()+ cos() (cos(ky) cos +sin (ky )sin z) (-1)
