hello my name is ardi and we are going
to solve
this complex system of equation
by using this calculator okay when you
solve a circuit
you will have a matrix of equation that
looks like this
and the problem is
solving this manually is a mess so you
need some tools to
what is it to solve it efficiently and
easily so we have this kind of matrix
here
we have four
two by two matrix here so we have two
equation with two variables
so the first thing that we need to do is
we give name to each of the numbers that
on the matrix
maybe let's give them to the number the
number here as a
and here sp
here as c and here sd
and v1 and v2 is just
unknown variables
but we need we give name to this also so
this is e and this is f
so we will have our matrix here becomes
a
b
c d
and then multiplied by v one and p two
so v one and v two
and that will equal to e
and
f
okay now we are going to solve this
using cramer's method
so cramer's method
what is grammar's method kramer's method
is just by
we got v1 here
by dividing delta 1
with delta
and what is delta 1 and delta we will
talk about it later
and v2 here will be delta 2
divided by delta okay
now the easiest thing to do is the delta
which is the determinant of this matrix
