pls help with matlab

The horizontal displacement with respect to time, I, as x(t) and vertical displacement y(t) are given X(t) = 2 y(t) = sin(t) For t=0 to 10 ms, determine the values of plot x() and y(t). Use the values to x(t) versus y(t). b) The gain versus frequency of a capacitive-coupled amplifier is shown below. Frequency (Hz) 20 Gain (dB) 34 40 Gain (dB) 5 10 30 32 34 Frequency (Hz) 2000 5000 8000 10000 80 100 120 34 34 32 30 12000 Draw a graph of gain versus frequency using a logarithmic scale for the frequency and a linear scale for the gain. Does interpolating given gain would improve the graph? How? c) For an R-L circuit, the voltage v(t) and current i(t) are given as v(t) = 10 cos(377) i(t) = 5 cos(377t + 60) Sketch v(t) and i(t) for t=0 to 20 milliseconds. What to Hand In.
