But what are the p...
Take a matrix A=(acbd), where a,b,c,d are numbers.
First find the determinant. This is ad-bc.
Now, rearrange the matrix to become (...
This will use the process of integration by parts.
First, notice that ln(x)=ln(x)*1.
So, the integral of ln(x) is the integral of ln(x)1. The process of integration by parts is; i...
Sound waves have mass, as they are the longitudinal (along the path of the wave) vibration shockwave of molecule, while light waves do not, as they are the transverse displacement of just energy.
Take any polynomial, eg/ y=x3+1/2x2-3x+9. Then dy/dx=3x,+x-3, i...
