Ok i have been given two trigonometric functions and asked to give them as phasors, and then calculate the average power supplied from this.(adsbygoogle = window.adsbygoogle || []).push({});

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?
