Hello, everyone. Tom from everystepcalculus.com and every stepphysics.com. Problem on Curl Divergence. Are they diverges or not and what is the answer of that. So let’s do it. Index 8 to get to my menu. Go down to curl. Don’t do the M,N,P system. Let’s do the P,Q,R system
right now. Depending on what your professor likes or does. Alpha to press anything in here. You have to press Alpha first. We’re going to put in 2 times Y and then Alpha X squared plus 2 times Z times Y, and then alpha Y squared. I always show you what you’ve entered,
you can change it if you want. I say it’s okay. Compute the curl first. Then we want to choose number 2. To the different formula. This is the system it’s not a crossproduct situation like it was in the curl. So each one is done partial of P with respect to partial of X. It turns out to be zero. The derivative of this is zero. Partial of Q with respect to Y turns out to be 2z. Partial of R partial with respect to Z turns out to be 0. So the answer is 2z. Now you want to compute it at a point. We can do that too, you can press one here, we can go to the and enter our point. Let’s enter alpha 1, alpha 5 and alpha 6. I show you again what you’ve entered, you can change it if you want. And these quotations marks are really parentheses for you. You’re substituting 6 for Z so you can put parentheses around the six on your test or homework.The answer is 12. Pretty neat, huh? Have a good one.
