If y= ⁻¹ ( a x-b x b x+a x ) , then d y d x is equal to
Options
- A0
- Ba b
- C-1
- D2
Correct answer
C. -1
Step-by-step solution
y= ⁻¹ ( a x-b x b x+a x ) = ⁻¹ ( a b- x 1+ a b x ) [Take b x common from numerator and denominator] array rlrl & = ⁻¹ ( - x 1+ x ) & [ Let a b = ] & = ⁻¹( -x )= -x & & [ a b = ] y & = ⁻¹ a b -x & d y d x & =0-1=-1 & array
