Using OCTAVE,

1. Write a computer program to graph the function,
(, ) = sin() + 1

2. Write a computer program to sketch the curve of intersection of the circular cylinder 2 + 2 = 4 and the parabolic cylinder = 2.

3. Consider the following system of linear equations.
− 0.5 + 0.875 − 0.113 = 1.121
0.25 − 56 + 0.8 + = 0
+ 0.112 − + = 2
0.2 − 0.3 + 0.4 + 0.5 = 121
I. Express the system of linear equations in the form,
= .
II. Using OCTAVE,
Write a computer program to find −1.

step-by-step explanation:

dong do iy iys a scram

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
