Integral Practice Problems. To see the solution, place the cursor on the

appropriate line and press "enter":

Ans1:=int((2*x^2-x+4)/(x^3+4*x),x);

Ans2:=int(exp(2*theta)*sin(3*theta),theta);

Ans3:=int(1/(y*(2-y)),y);

Ans4:=int(t^2*cos(3*t),t);

Ans5:=int(x^3*exp(x^2),x);

Ans6:=int(x*5^x,x);

Ans7:=int((x-1)/(x^2+1),x);

For Problem 8, Maple will give an inverse hyperbolic arc tangent. To verify

your solution, here is the integral using the substitution:

Ans8:=int(1/((u+1)*(u-1)),u);

subs(u=sqrt(x+1),Ans8);
