Graph of voltage over time

[srfrgrl727]

if you have have the equation v(t)=30sin(63t- pi/2) where max voltage is 30 and the period is 100ms. at t=0 v is 30 (sorry i could give you a graph) how would a DC shift of 10 volts change the graph

This should be moved to the homework help forum.

Ask yourself these questions.

- What would a DC offset of 10 V do to the algebraic representation of the voltage with respect to time (i.e. how would your equation for the voltage change).

- Hence, what would this change mean graphically. If it is not immediatley obvious, substitute some time values and plot the graph yourself.
