Title: Find the first derivative of y with respect to x Post by: Jessa Marasigan on Dec 11, 2020 1.) 3x^2-xy+4y^2-2x+1=0
2.) x sin xy -3x-5=0 3.) x-y ln xy = 10 4.) tan^-1 sqrt(y) - 3x + 2y = 0 Title: Re: Find the first derivative of y with respect to x Post by: bio_man on Dec 11, 2020 Hi Jessa,
So I think I got 1 through 3 for you (below), but for #4, could you confirm if this is what the function looks like before I start: (https://biology-forums.com/gallery/42/6_11_12_20_9_37_51.png) (https://biology-forums.com/index.php?action=gallery;sa=view&id=42268) \(\arctan \left(\sqrt{y}\right)-3x+2y=0\) * arctan means inverse tan-1 Title: Re: Find the first derivative of y with respect to x Post by: Jessa Marasigan on Dec 13, 2020 thank you so much for helping me! yes, that's number 4.
Title: Re: Find the first derivative of y with respect to x Post by: bio_man on Dec 13, 2020 thank you so much for helping me! yes, that's number 4. Okay, so in that case the first and last term become 0, and the middle term becomes -3, leading to: -3 = 0, which doesn't make sense :-[ Really not sure about that one, have you been given the answers by any chance? |
