Question 25683: Hi, i have this question and i dont know how to start it or what i have to actually find. this is the question;
Two vibration, x1=3sin(10t+π/6) and x2=2cos(10t- π/6) where t is in seconds, are superimposed. Determine the time at which the amplitude of the resultant vibration, x1+x2 first reaches a value of 2.
thanks
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
One way to do it would be to graph the sum of the curves
and find the 1st intersection of this sum with the line
y=2. I get an answer of t=0.19834196... radians
Cheers,
