It is an integrator so the input is converted into triangle wave.

Specify the input signal.

An integrator follows as stop pattern so if i/p square then o/p triangle but input is now showing zero.

Input is not cleared then how are you say that output is triangular?

When the input is rectangular wave then the output is a trangular wave.

Data is insufficient to find the solution.

It's an integrator where capacitor charges and discharges which produce a sawtooth waveform. Then the sawtooth waveform is given to the comparator which gives a square waveform. So it's not a triangular waveform.

Here what is the input?

When I/P is unit step then O/P is ramp signal. When I/P is Square wave then O/P is triangular wave. Because circuit is integrator But in this question we do not have given then answer will be Data insufficient.

Need a required input signal but if it is sin wave the output is cos wave.

Because it is a op-amp as differentiator circuit.
