The period of ( - 1 3 ^3 ) ( 1 3 - ^2 )⁻¹ where ^2 1 3 is
Options
- A3
- B2 3
- C2
Correct answer
A. 3
Step-by-step solution
( - 1 3 ^3 ) ( 1 3 - ^2 )⁻¹ where, ^2 1 3 = ( - 1 3 ^3 ) ( 1 3 - ^2 ) = 3 (3 - ^3 ) 3 (1-3 ^2 ) = 3 3 = ( 3 - ^3 1-3 ^2 )= ( +3 )= 3 ( 3 + ) So, the period of the given function is 3 .
