In this question (brainly.com/question/12792658) I derived the Taylor series for
about
:

Then the Taylor series for

is obtained by integrating the series above:

We have
, so
and so

which converges by the ratio test if the following limit is less than 1:

Like in the linked problem, the limit is 0 so the series for
converges everywhere.
A) (-2,4)
first multiply 2nd eqn by 2 and subtract it from eqn 1st then u will get x then put x in ist eqn then u will get y.
Your answer would be x = -15.8994.
To get this, you first add 7 to each side making the equation -4.818 = x/3.3
Then, you would need to multiply each side by 3.3 to get x by itself.
Your answer would be -15.8994.
