This question is example of product rule. To simplify need to define two terms u=4x+1 and v=ln(3x+1). Each term is then differentiated. du/dx=4. To differentiate v, need to define another term a=3x+1, the...

Integrate each term in terms of x, then integrate each term in terms of y Make sure you state in what form you are integrating. Remember if you are integration in terms of y, the x values are constants an...

Electronegativity is the measure of how strongly an atom attracts a bonding pair of electrons to itself. As group 7 is descended, the electronegativity decreases. This is because the size of the halogen a...
