Figure shows the spectrogram of a chirp signal of the form? x[n] = sin (? 0 n

Question:

Figure shows the spectrogram of a chirp signal of the form?

x[n] = sin (?₀n + 1/2?n²).

Note that the spectrogram is a representation of the magnitude of X[n, k], as defined in Eq. (??), where the dark regions indicate large values of |X[n, k]|. Based on the figure, estimate ?₀ and ?.
