I need help using Scilab for these problems

I wo continuous signals are given as follows:
x1 (t) = sin
; X2 (t) = sin
Please write a Scilab program to do the following:
Sampling the signals x1 (t) and x2 (t) for 0
Create a new signal s(t):
# 200 with step size 1
s (t) = x1(t) + X2(t)
8. Use Scilab function wiff) to design a low pass filter with following requirements:
Order of the filter - 33; Use Kaiser Window, cut off frequency = 0.2, and trade-off between main-lobe and side-lobe
parameter is 5.6
9. Filter the signal s(t) by using Scilab function:
y = convol(wft,s)
Where wit is the vector of designed filter coefficients, s is the input signal, and y is the output signal or filtered
10. Plot the signal s(t) and y(t) with following requirements:
Plot both signals in the same window
Signal s(t) is in the upper half of the window with title: "Sum of Two Sinusoids"
Signal y(t) is in the bottom half of the window with title: "Filtered Signal By a Windowed FIR
Label the horizontal axis with "Time"; and vertical axis with "Amplitude" for both graphs
You can find an example for plotting these graphs in this unit's lecture.
