I got part 1 wrong?

Question

My limits were incorrect. I got my upper and lower limits as 2 and 546 by plugging in 25 and 9 to 627-r^2

What would be the indefinite integral and in terms of u?

Answer 2

Your limits are correct. Maybe its the way you wrote the function. Try writing as below

= ₅₄₆∫² -½(√u) du

Next find antiderivative but do not substitute the limits

= -½ ₅₄₆∫² (u^½) du

= [-½ * u^(½+1) / ((½+1)]  ₅₄₆|²

= [-½ * ⅔ u^(3/2)]   ₅₄₆|²

= [-⅓√u³] ₅₄₆|²
