1. For the figure given on the right, the value of cot A is   tan C   c / b   sin A / cos A   a / c   cos C / sin C   Hint Half-n-half Clue   2. From the figure, the value of cot C + cosec C is   c/a + b/c   (a + c)/b   a/c + c/b   (a + b)/c   (c + b)/a   Half-n-half Clue   3. From the figure, the value of sin2 A + cos2 A is   b/a + c/b   a/b + c/b   (a/b + c/b)2   1   (b/a + c/b)2   Half-n-half Clue   4. tan A / sin A =   cos A   sec A   1 / sin A   sin A   cosec A   Half-n-half Clue   5. cosec A / sec A =   sin A + cos A   cot A   sin A   tan A   cos A   Half-n-half Clue   6. For the figure given on the right, which of the following relationships is true :   tan A = a / b   sec A = b / a   cos A = b / c   cot A = c / a   sin A = a / c   Half-n-half Clue   7. From the figure, the value of cosec A + cot A is   a/(b + c)   (b + c)/a   (a + c)/b   b/(a + c)   (a + b)/c   Half-n-half Clue
