Definite Integration question

2018 · 16 Apr · Shift 1 · Q26

JEE MainMathematicsDefinite IntegrationMCQ+4 / −1
If f(x)=∫0xt(sin⁡x−sin⁡t)dt   f(x) = \int\limits_0^x {t\left( {\sin x - \sin t} \right)dt\,\,\,}f(x)=0∫x​t(sinx−sint)dt then :
  1. A
    f'''(x) + f''(x) = sinx
  2. B
    f'''(x) + f''(x) −-− f'(x) = cosx
  3. C
    f'''(x) + f'(x) = cosx −-− 2x sinx
  4. D
    f'''(x) −-− f''(x) = cosx −-− 2x sinx
