The differential coefficient of ⁻¹ t 1+ t ^2 w.r.t. ⁻¹ 1 1+ t ^2 is
Options
- A1 t 0
- B-1 t 0
- C1 t R
- DNone of these
Correct answer
B. -1 t 0
Step-by-step solution
y= ⁻¹ ( t 1+t^2 ) , z= ⁻¹ ( 1 1+t^2 ) -1 t 1+t^2 1 and 0 ( 1 1+ t ^2 ) 1 t R let ⁻¹ ( t 1+t^2 )=0 (- / 2, / 2) t 1+t^2 = = 1 1+t^2 (i) if (0, 2 ) , then y= , z= d y d z =1 (ii) if (- 2 , 0 ) , then y= , z=- d y d z =-1
