The electrical rules inspection is also error-free. Which great god can explain it to me? It's urgent.

Make a function signal generator to display square wave, triangle wave and sine wave?

I used 741.

You have to do it one level at a time. First, see what waveform the 6-terminal of U1 can output. If the first output is wrong, you don't need to do it later.
