this is what i got..
=5sin(50t+60)----- where pi/3=60 degrees
we need to express i1 in cosine form. the rule for converting sine to cosine is to subtract 90degrees. hence,
then we need to convert in phasor form, using scientific calculator..
i1=5/_-30------>> i'm not sure how to write it here, i hope u understand
i(total)=i1 + i2
=5/_-30 + 6/_0
=10.33 - j2.5-------->>you will get the answer in rectangular form
=10.628/_-13.6------>>in phasor form
i hope this will help you.
