LRAM
the method of approximating a definite integral over an interval using the function values at the left-hand endpoints of the subintervals determined by a partition

Simpson's Rule
Δx/3 (f(x₀)+4f(x₁)+2f(x₂)+4f(x₃)+...+4f(Xn-₁)+f(Xn))
Fundamental Theorem of Calculus (part 1)
Let f be a continuous real-valued function defined on a closed interval [a, b]. Let F be the function defined, for all x in [a, b], by
-b->af(x)dx
a->b f(x)dx
0
a->a f(x)dx
b->a cdx
c(b-a) where c is any constant
b->a [f(x)+g(x)]dx
b->a f(x)dx+ b->a g(x)dx
b->a cf(x)dx
c b->a f(x)dx where c is any constant
b->a [f(x)-g(x)]dx
b->a f(x)dx-b->a g(x)dx
b->a f(x)dx
c->a f(x)dx+b->c f(x)dx
then b->a f(x)dx>_0
If f(x)>_ 0 for a<_x<_b
then b->a f(x)dx>_b->a g(x)dx
If f(x) >_ g(x) for a<_x<_b
then m(b-a)<_b->a f(x)dx<_M(b-a)
If m<_f(x)<_M for a<_x<_b
