I started in on literally the first section of the AP Calc AB review program and there’s already a mistake in the first or second math problem. Now I’m suspicious of the rest of it.
sqrt(16)/9 is not 4/3. It’s 4/9. What the heck?
Hi @Adam_Buckridge, you’re right, and thanks for catching it! √16 / 9 = 4/9, not 4/3. The last line mistakenly took the square root of the denominator, too. We’ve corrected it, and the example now shows 4/9.
As a heads-up, the AP Calculus AB course is currently in early access, which is why it was offered at a discount. It hasn’t gone through our full review yet, and that review is underway. Reports like yours help a lot. If you spot anything else that looks off, please use the Feedback button on the page. It sends our content team a direct link so they can fix it as quickly as possible.
Thank you,
