Construct a Schmitt Trigger using the 741 Op Amp

Draw the Schmitt Trigger circuit you constructed. Identify the values of all components

To construct the circuit above I am going to use the following components and voltages:

$R_1 = (1.01\pm0.01)\ k\Omega$
$R_2 = (1.01\pm0.01)\ k\Omega$
$R_3 = (5.10\pm0.01)\ k\Omega$
$\mbox{OP}\ \mbox{AMP}\ 741$
$V_{ref} = (+11.90\pm0.01)\ V$
$V_{cc} = (+11.90\pm0.01)\ V$
$V_{ee} = (-12.11\pm0.01)\ V$

Graph $V_{out}$ as a function of $V_{in}$ . Is there a hysteresis loop?

Identify the input voltage threshold levels at which a $V_{in}$ will produce $V_{out} \approx V_{cc}$

Compare the threshold values to what is expected.
