SETTING THE HYPOTHESES , THE VARIABLES' VALUES AND THE RELATIONS BETWEEN VARIABLES (2nd PROBLEM: SAME WIDTHS, DIFFERENT FREQUENCIES)    

HYPOTHESIS:
The two oscillations have the SAME direction, the SAME width, take place around the SAME point, DO NOT HAVE DIFFERENCE in their phases,
BUT have DIFFERENT frequencies.      

x1[t_] := A1 * Sin[w1 * t]

x2[t_] := A2 * Sin[w2 * t + f]

f = 0 ;

A1 = A2 ;

SETTING THE VARIABLES' VALUES:
SET values for the oscillations' widths and frequencies: (EACH ONE of you can set the values he / she prefers)  

A1 = A2 = 20

20

w1 = Pi/3

π/3

w2 = Pi/4

π/4
