Question

CosA+cotA=m and cot A-cosA=n then prove that (m2-n2)2=16mn

Answer 1

this the answer for that

Answer 2

Step-by-step explanation:

2 COSA ) ² = ( casa ) ² 2 * LotA + COSA = on and cotA = 00317 = n a . shut that cat's - cos²A - Cot ²A . L - 3²A . b . prove that ( min ) ² C. prove that seca - find 16mm ( m + n ) 2 4mn
