Create program statements in Python that compute a vector of $y$ values based on the following formulas:

$($a$)y=\frac{6t^3-3t-4}{8sin(5t)},0\mathrm{.}1t0\mathrm{.}25$

$($b$)y=\frac{3t-2}{4t}-\frac{}{2}t,1t5$

where $t$ is a vector of $10$ values in the range prescribed. Create a plot of $y$ versus $t$ for each of the above.
