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