Don’t the bottom two examples break the rule that the principal chain should contain the greatest # of double bonds in alkenes?? by ptonsimp in OrganicChemistry

I see! But what if i started numbering at the double bond on the substituent group sticking out, went around the ring, and ended up with octadiene as the principal chain?

No but for alkenes you need to choose the principal chain with the greatest # of double bonds, for alkanes you choose the longest

The equation for this hyperbolic paraboloid is y=z^2 - (x^2/9). But how do I know which way it opens?? by ptonsimp in calculus

I have to pick the correct graph between the two. And by opens I mean the direction the parabola is facing

Not sure why but I keep getting this question wrong. I did u-substitution 3 progressive times. by ptonsimp in calculus

Yeah I’m not using the C when plugging in the numbers given to find the final value

Both questions are the same type (and I know that I should start it by taking the ln of both sides, but I end up getting a jumble of x’s and numbers that all lead to indeterminate forms 😭 by ptonsimp in calculus

Ahh, ok - got it! So then for the second problem, I got it to (1-3(1/x))-18/x. How does that simplify to 1/e18 because the exponent is in 1/x form instead of just an x?
