Sec2A - Tan2A Definition of Sec and Tan = 1/Cos2A - Sin2A/Cos2A Combining Fractions = (1 - Sin2A) / (Cos2A) Apply Double Angle Formula = (1 - 2SinACosA) / (Cos²A - Sin²A) Make use of...

This is a first order differential equation, but initially it is not solvable as both the X&Y's can't be separated from eachother directly. An integrating factor is a specific value that when multipli...

This equation is asking us to find the value(s) of x that when substituted in place of x in the equation x²-4x+3 the computed value should equal 0. There three potential methods of solving this...

I would say the main difference here is that eukaryotic cells (e.g. animal cells) have a nucleus and membrane-bound organelles, whereas prokaryotic cells (bacteria and archaea) have no nucleus and no memb...
