A curve crosses the x-axis when y=0, if we put that into the equation above we get the quadratic equation 0=8-4x-2x². The solutions to this equation are the values of x where y=0, which is the ...

A stone, of mass m, falls vertically downwards under gravity through still water. At time t, the stone has speed v and it experiences a resistance force of magnitude lmv, where l is a constant.  QUESTION:...

The chain rule is a method that allows you to differentiate a function of a function, which can be of the form y = f[g(x)]. That is, g is a function of x and f is a function of g, which in turn is a funct...

Find the values of y such that log₂(11y-3)-log₂3-2log₂y = 1

Power law: 2log₂y = log₂y²

Product law: log₂(11y-3) -...

In differentaition, it is all about multiplying and taking away. Look at the first integer and the number that it is in the power off. You have to simply times the integer with the power of number and the...
