Integrate ( (sqrt (x^2 - 9))/x )( exp x^2 )( cos 7x )( sin(x^4 + 5x^2 + 100) ) dx

with upper limit = 3 and lower limit = -3

I have tried to use integration by part and set u = ( (sqrt (x^2 - 9))/x )( exp x^2 ) and

dv = ( cos 7x )( sin(x^4 + 5x^2 + 100) ) dx

with upper limit = 3 and lower limit = -3
