9B Sample 1:
3.a) Step 2, should say 2 - cos(x), not 1 - cos(x) 4. Foundation, would be better to write it as sin^2(x) + cos^2(x) = 1 since you remind them of this in each example before using it anyways 4.b) I think it would look better if you wrote \int 1 dx instead of just \int dx in steps 1 and 3 4.b) Make the size of the final integral in step 4 larger 6.b) Should be limit as a approaches 4 from the left only 7. Foundation, should have a dx at the end of the equation for ds 7.b) Why not solve it using u-sub directly instead of trig sub to start?
9B Sample 2: 4. This is completely blank. 5.b) Just compute 27^2/2^2 = 729/4, would look better I think 7.a) and b) Why convert the limit from a to x, since a ranges over real numbers also so l'Hopital's rule holds. 7.b) Should be limit as a approaches 0 from the right only
