    Undergrad Finding the period of trig series analytically?

    Sorry, I'm still confused. For this example... x(t)=4sin(15t)-3cos(9t+1.1) ...I have graphed this in MATLAB, and graphically found a period of about 2.1. I am trying to apply what you suggested, but can't figure out how to calculate the period of 2.1...

    High School Calculating the period of a harmonic function

    What if you have a harmonic function with both cos and sin? such as: x(t)=4sin(15t)-3cos(9t+1.1) can you find the period of this analytically? I have found this has a period of 2.1 by plotting it in MATLAB, but can't figure out how to calculate this analytically...

    Undergrad Finding the period of trig series analytically?

    Is there a way to calculate the period of a trigonometric series (like the one below) analytically? x(t)=5sin(16t)-4cos(8t+3.1)
