Definite Integration question

2022 · 25 Jul · Shift 2 · Q42

JEE MainMathematicsDefinite IntegrationNumerical+4 / −1
Let fff be a twice differentiable function on R\mathbb{R}R. If f′(0)=4f^{\prime}(0)=4f′(0)=4 and f(x)+∫0x(x−t)f′(t)dt=(e2x+e−2x)cos⁡2x+2axf(x) + \int\limits_0^x {(x - t)f'(t)dt = \left( {{e^{2x}} + {e^{ - 2x}}} \right)\cos 2x + {2 \over a}x}f(x)+0∫x​(x−t)f′(t)dt=(e2x+e−2x)cos2x+a2​x, then (2a+1)5 a2(2 a+1)^{5}\, a^{2}(2a+1)5a2 is equal to ‾\underline{\hspace{2cm}}​.
