Here we have a product of two things, so we will be using the product rule of differentiation. This is: for y=u(x)v(x), where u(x) and v(x) are funtions of x, dy/dx = u'(x)v(x) + u(x)v'(x). So in this ...
We can't integrate cos^2(x) as it is, so we want to change it into another form. We can easily do this using trig identities. 1) Recall the double angle formula: c...
There's a nice trick here you can do, treat the equation as 1*ln(x) then intergrate by parts.
Differentiating ln(x) gives 1/x, while intergrating 1 gives x
So your left with...
First off, an explicit definition needs to be understood. An explicit definition is the standard form in which many equations are found:
y = f(x) (1)
for example: y=...
