Where is equation?

[Ajinkya Shelke]

v= - 0.056139*cos(t*w1) - 3.3986*cos(t*w2) - 0.41655*cos(t*w3) - 1.1272*cos(t*w4) - 0.0015669*cos(t*w5)

w1 w2 w3 w4 w5 are known

Answer 1

[KALYAN ACHARJYA]

w1=? % Defined all data
w2=?
w3= ?
w4=?
w5=? 
t=0:0.01:18;
v=- 0.056139*cos(t*w1)-3.3986*cos(t*w2)-0.41655*cos(t*w3)-1.1272*cos(t*w4)-0.0015669*cos(t*w5);
plot(t,v);
