這題偏微分幫幫忙了🙏

Question_10 If z is defined implicitly as a function of x and y by the equation 2x² - 3y² + z² + 6xyz = 1, then Əz ax 2z+6xy 1. 4x+6yz 2. 3. - 2z+6xy 4x+6yz 4x+6yz 2z+6xy 4x+6yz 4. - 2z+6xy

有人解得出這三題偏微分題嗎？

幫我畫出正確答案

4. The cross-linking reaction of polyvinyl alcohol forms four water molecules for every B(OH)4 that cross- links two polymer chains. Given the sections of polyvinyl alcohol chains below, sketch how B(OH)4 cross-links the chains. Through what atom chain linkages are the C-C polymer backbones connected? CH CH₂ H O-H O-H H H CH₂ H-O. +B (OH)4 H H CH₂

剛開始學隱函數，想問框起來的部分是用什麼rule呢？課程裡面是說用chain rule，但我看不太懂是怎麼寫成那樣的

Example 1: Let x² + y² = 25, , find dy == dx , dx dy and the equation of the tangent at (3, 4). Solution: 2x+2y 33 dy dx = 0 dx 2x dy |+ 2y = 0 X dy m = dx dy dx\(3,4) 3 -¾³½⇒(y−4) = −²/√(x − 3). =- 4 dx dy X

求解這四個的正確命名🆘

1. Give the IUPAC name for each of the following structures. (20 points) (1) (2) (3) Br (4) ON. CH NO

要用什麼test來判斷這題會不會收斂

想問第一題 答案為什麼是A?藍綠菌應該是在真核藻類前面吧
