Blababa [14]

Answer:

v =-28

Step-by-step explanation:

-18 - 3 /4 v = 3

Add 18 to each side

-18+18 - 3 /4 v = 3+18

-3/4 v = 21

Multiply each side by -4/3 to isolate v

-4/3 *-3/4v = 21*-4/3

v =-28

Answer:

See below

Step-by-step explanation:

$\frac{1}{1-cos A} - \frac{1}{1+cos A} =2 cosec A cot A \\ \\ L. H. S.= \frac{1}{1-cos A} - \frac{1}{1+cos A} \\ \\ = \frac{1+cos A - (1 - cos A)}{(1-cos A)(1+cos A)}\\ \\ = \frac{1+cos A - 1 + cos A}{1-cos^{2} A}\\ \\ = \frac{2cos A }{sin^{2} A}\\ \\ =2 .\frac{1}{sin A}.\frac{cos A }{sin A}.\\ \\ = 2.cosec \: A.cot \: A \\ \\ = R.H.S$
