Title: How do you use implicit differentiation to solve these? Post by: davasour on Dec 16, 2012 a) 16x^2+49y^2=784
b) (4x^2+5xy-y^2)=8 I thought the answer to this was y1=8x+y/5x-2y but the program says its wrong. Please explain I don't understand implicit differentiation at all. for a I also have to solve the equation explicitly for y and differentiate to get dy / dx in terms of x. (Consider only the first and second quadrants for this part.). how would I do this? Title: How do you use implicit differentiation to solve these? Post by: juiewolfe5 on Dec 16, 2012 Differentiate with respect to x for both,
a) 32x + 98yy' = 0 y' = -16x/(49y) b) 8x+5y+5xy'-2yy' = 0 y' = (8x+5y)/(2y-5x) Title: How do you use implicit differentiation to solve these? Post by: finakatarina on Dec 17, 2012 a) dy / dx = - 16x / (49y)
b) dy / dx = (- 5y - 8x) / (5x - 2y ) Title: How do you use implicit differentiation to solve these? Post by: lenorefrancis on Dec 17, 2012 Content hidden
