It's not possible to say without input waveform. Data is insufficient to answer.

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.

Whatever the input inspite output is always a triangular wave in the integrator.

Insufficient data, please rectify the question for effectiveness.

If we think logically, we have capacitor in feedback so capacitor here initially charge when supply is given and than it discharge so we get two types of wave either saw tooth and triangular but here capacitor discharge slowly. So answer is triangular waves.

The voltage is also AC.

Input should be square wave then integration of square wave (can be represented by unit step) gives ramp function i.e triangular.

The input must be square wave to get triangle wave at the output.

It's input signal is in square wave.

Because it is a op-amp as differentiator circuit.
