voltage is given by v(t)=10sin(1000?t+30?)Vv(t)=10sin(1000?t+30?)V. Part A Select the correct expression for the cosine function to express v(t)v(t). v(t)=10cos(1000?t?30?)v(t)=10cos?(1000?t?30?)v(t)=10cos(1000?t?90?)v(t)=10cos?(1000?t?90?)v(t)=10cos(1000?t?60?)v(t)=10cos?(1000?t?60?)v(t)=10cos(1000?t+90?)v(t)=10cos?(1000?t+90?)v(t)=10cos(1000?t+60?)v(t)=10cos?(1000?t+60?)
