    Hi all,

    I need to plot a curve for this expression.

    V1 = 120 sin ωt + 40 sin 3 ωt volts

    Any help appreciated.

    That's a bit difficult without $\displaystyle \omega$, but not impossible if you are willing to label your graph appropriately. Have you tried plotting some points? Contemplating the period? etc.
