we can use cosine also in electrical quantities.
But we can't go for the other waves what you specified above.

Because we have some advantages with sine and cosine waves compared to others,

such as the differentiation and integration of these waves(sine&cosine) leads to same wave form again with some shift. Implies the nature of waveform not changed.
Because our electrical system consists of integro-differential equations.

If you differentiate triangular wave it leads to a rectangular wave for which the load performance may be poor in that context.

So, we can use only sine and cosine waves in EE.

Sine wave forms we can indicate the maximum and minimum amplitude and its variation with respect to time.

RMS value of sine wave is more than the other wave like square, triangular etc.

The emf induced at power plants is sinusoidal AC, so it is not because of our choice. It is the natural simplest AC waveform that we obtain.
