Ok i have been given two trigonometric functions and asked to give them as phasors, and then calculate the average power supplied from this. v = 311 sin (200t+7[tex]\circ[/tex]) V i = 14 sin (200t - 16[tex]\circ[/tex]) A I'm used to the trigonometric functions being in the cosine form, what difference will this make? I believe it would be: v = 311 [tex]\angle7[/tex] and i=14[tex]\angle-16[/tex] If it was given in the cosine form. And from there it would be possible to work out the average power. Can anyone help me with this?? Also i know i might need to give the magnitude in RMS form. EDIT: Is it 83 degrees instead? and 74 for i?
