Question: A particle is moving in a straight line with simple harmonic motion. The period of the motion is (3pi/5)seconds and the amplitude is 0.4 metres. Calculate the maximum speed of the particle. ...
Any odd integer can be represented by 2m+1 for some integer m (can prove that 2m+1 is always an odd number if needed). (2m+1)2=4m2+2m+2m+1=4m2+4m+1=4m(m+1)+1 simple factor...
First assess that the initial case of where n = 1 is true. In this case, 6+9=15=53, so we can see that the case is true.We can then assume that 6k+9 is a multiple of 5, so we can let 6...
An important rule to remember when dealing with complex numbers is that if the complex number a+bi is a root of a polynomial, then the complex conjugate (a-bi) must also be a root of this polynomial.There...
