Firstly we need to expand out y into a series of terms to make it easier for us to compute the derivative . You multiply out the brackets to get y=(x³-3x²+4x-12)/2x then we divide ea...

A-Level Biology has probably the most content of any of the A-Level sciences! Its tempting to memorise all the content in the textbook but in reality some textbooks will have extra information that is no...

Throughout both "The Whitsun Weddings" collection and the novel “The Great Gatsby” the themes of love and fantasy are frequently explored and shown by both poet and author to be somewhat interch...

they don't have a nucleus, the DNA is present in cytoplasm. prokaryotic cell has a cell membrane that controls movement of molecules in and out of the cell. prokaryotic cells also have cell walls that pro...

z* is the complex conjugate of z therefore z* = x - yi. So 16 + 32i = 5(x + yi)-3(x - yi), real: 16 = 5x - 3x => 16=2x => x=8, imaginary: 32 = 5y + 3y => 32 = 8y => y=4, therefore z = 8 + 4i.<...
