If I is the greatest of the definite integrals I1=∫10e−xcos2x dx, – InterviewSolution

1.	If I is the greatest of the definite integrals I1=∫10e−xcos2x dx, I2=∫10e−x2cos2 x dxI3=∫10e−x2dx, I4=∫10e−x22dx, then
Answer» If I is the greatest of the definite integrals $I_{1} = \int_{0}^{1} e^{- x} c o s^{2} x d x, I_{2} = \int_{0}^{1} e^{- x^{2}} c o s^{2} x d x$ $I_{3} = \int_{0}^{1} e^{- x^{2}} d x, I_{4} = \int_{0}^{1} e^{\frac{- x^{2}}{2}} d x, t h e n$
