Step 1: Recall the rule of indirect speech.
When the reporting verb ("told") is in the past tense, the verb inside the reported clause must generally be shifted one tense back.
Step 2: Apply tense change.
Direct speech: "I \underline{am thinking}…" → present continuous.
In indirect speech (past reporting verb), present continuous becomes past continuous: "was thinking."
Step 3: Adjust time expression.
"This weekend" changes to "that weekend."
Step 4: Construct final sentence.
Rafi told Mary that he \underline{was thinking} of watching a film that weekend.
Final Answer:
\[
\boxed{\text{was thinking}}
\]
Given an open-loop transfer function \(GH = \frac{100}{s}(s+100)\) for a unity feedback system with a unit step input \(r(t)=u(t)\), determine the rise time \(t_r\).
Consider a linear time-invariant system represented by the state-space equation: \[ \dot{x} = \begin{bmatrix} a & b -a & 0 \end{bmatrix} x + \begin{bmatrix} 1 0 \end{bmatrix} u \] The closed-loop poles of the system are located at \(-2 \pm j3\). The value of the parameter \(b\) is:
