Question

Radical cosx * Sinx dx. U=? (Don’t integrate)

Answer 1

u = cos x

Explanation:

I assume you mean `sqrt cos(x) * sin(x) \ dx` because if both are under the radical the result is nonelementary.

If I have it right use `u=cos(x)` with `sin(x) \ dx = - du` and the rest works out nicely.

Happy solving
