Question

Integration x sin (2x^2)dx

Answer 1

Answer:

Answer is -(1/4)Cos(2x^2) + C

Explanation:

let integration sign can be written as "int" because no sign is awailable for it.

explaination-

I = int (xSin(2x^2)dx)........(i)

let 2x^2 = t

4xdx = dt

xdx = dt/4

put in equation .....(i)

I = int((1/4)Sin(t)dt)

= - (1/4)Cos(t) +C where C is conatant.

= -(1/4)Cos(2x^2) + C is the required answer..
