The term X-ray applies to radiation over a range of wavelengths. But a typical X-ray has a frequency of about 3 x 1017 Hz. Make a sine wave model of an X-ray as a function of time t in seconds. Use an amplitude of 1. (Express numbers in exact form. Use symbolic notation and fractions where needed. Large numbers require scientific notation. Use multiplaction dot instead of " x " symbol. Let y = f(t) and give the equation in terms of y and 1.)

what it means to have a change in amplitude and a change in period.

If p = -1.4, simplify the expression tan (tan-(p)).

When a key is pressed on a touch-tone telephone, the keypad generates two pure tones, which combine to produce a sound that uniquely identifies the key. The figure shows the low frequency f1 and the high frequency f2 associated with each key. Pressing a key produces the sound wave y = sin(2nfzt) + sin(2xf2t).
