The value of the expression (cos 6 θ + sin 6 θ – 1) (tan 2 θ + cot 2 θ
| The value of the expression (cos6θ + sin6θ – 1) (tan2θ + cot2θ + 2) is :
A. -1
B. 1
C. 0
D. -3
Right Answer is: D
SOLUTION
Since the options are given in constant, so, we can check the value by putting the value of θ.
Let θ be = 45°
Required, by putting the value of θ
