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