Question

What is the resultant of parallelogram law of vector?​

Answer 1

So resultant of vectors A and B = √A²+B²+2ABcos a

And if the resultant R of the vector subtends an angle C with vector A ,then

Tan C =B sin a/A+B cos a

Answer 2

$\huge\underline\bold{AnSwEr,}$

So resultant of vectors A and B = √A²+B²+2ABcos a

So resultant of vectors A and B = √A²+B²+2ABcos aAnd if the resultant R of the vector subtends an angle C with vector A ,then
