∫sin2xsin2xdxIntegration by substitutionSome integrals can be solved by using substitution.By substitution we change the variable of integration to a new variable and a simpler function that can be integrated. Consider f(x) If the integral is of form ∫g(x)f(x)dx ...
令t=x^2, \frac{dt}{ dx}=2x\Rightarrow dt =2x dx 于是, \int x \cos x^2dx=\int \cos x^2 \cdot xdx=\int \cos t \cdot \frac{1}{2}dt 接着就简单了, \int \cos t \cdot \frac{1}{2}dt =\frac{1}{2}\int \cos tdt =\frac{1}{2} \sin t=\frac{1}{2} \sin ...
