# Help with the waves in an integrating operational amplifier?

What I'm wondering is ...

What wave signal is obtained when introducing a square and a triangular wave and why does this happen?

I understand that if I enter a sinusoidal I will obtain the integral of sinus, but what happens with those two signals?

An ideal integrator will produce (from a square wave) a triangular wave.

Why? because the integral of a straight horizontal line is a line sloping upwards.

eg, y = 2 integrates as y = 2t

An ideal integrator will produce from a triangular wave a x² (exponential) wave

Because the integral of a straight line at an angle, eg, y = 2t, is a y = t² wave.
