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