✏️ Task

Plot a graph of the function

$$ y(t) = \sin \omega t + \cos \omega t $$

where the user can specify the value of $\omega$ and the range of $t$.

The graph should be updated in real-time as the user changes the value of $\omega$ or the range of $t$.

✨ Main features

Besides the main task, the application also includes the following features:

• Shared preferences to save the last entered values of $\omega$ and $t$ range.
• A button to reset the values of $\omega$ and $t$ range to the default ones.
• A button to download the $\omega$ and $t$ range values as a .json file.
• A button to upload the $\omega$ and $t$ range values from a .json file with the pop-up confirmation window.
• Adaptable optimized plot of the function $y(t)$.
