These integrals don't make any sense. I know the basics but these are out of my legaue. I don't even know how to write the integral for that it has a top number and a bottom number to it. So ill give it a shot :
1) ∫^1 and the bottom is 0 then (4x^3 - 2x)dx
2) ∫^pie(3.14) and the bottom is pie/2 then (sin2x dx)
3) ∫^2 and the bottom is 0 then [3dx/ (4x +1)^1/2]
I know its confusing to read but i really need help on this to be ready for my quiz. So thanks for the help.
