then a is equal to :
Then, for an arbitrary constant C, the value of J – I equals
Ax + B log sin(x - α)+ C, then value of (A, B) is- a)(- cos α, sin α)
- b)(cos α, sin α)
- c)(- sin α, cos α)
- d)(sin α, cos α)
Correct answer is option 'B'. Can you explain this answer?

Write sinx = sin((x-α)+α) and expand.
equals (for some arbitrary constant K)
Let F(x) be an indefinite integral of sin2x.STATEMENT-1 : The function F(x) satisfies F(x + π) = F(x) for all real x. becauseSTATEMENT-2 : sin2(x + π) = sin2x for all real x.- a)Statement-1 is True, statement-2 is True; Statement-2 is a correct explanation for Statement-1.

Step:-1 take out x^4 from (x^4 +1)
step:-2 already we have x^2 so, now it becomes x^5
step:-3 now divide numerator by x^5 it becomes 1/x^5
step:-4 in denominator we will have {1+ (1/x^4)} put it as Y and then find dY/dx
step:-5 now solve carefully you will have answer
