Explanation
| $$ \begin{aligned}0.5e^jp\frac{i}{4}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}0.5e^j\frac{ip}{4}\end{aligned} $$ | |
| ① | Multiply $p$ by $ \dfrac{i}{4} $ to get $ \dfrac{ ip }{ 4 } $. Step 1: Write $ p $ as a fraction by putting $ \color{red}{1} $ in the denominator. Step 2: Multiply numerators and denominators. Step 3: Simplify numerator and denominator. $$ \begin{aligned} p \cdot \frac{i}{4} & \xlongequal{\text{Step 1}} \frac{p}{\color{red}{1}} \cdot \frac{i}{4} \xlongequal{\text{Step 2}} \frac{ p \cdot i }{ 1 \cdot 4 } \xlongequal{\text{Step 3}} \frac{ ip }{ 4 } \end{aligned} $$ |
