Question

ss

Answer 1

okay:move the y's to one side and on the other

Answer 2

so you get y-y^7=5x^2

Answer 3

when you derive you replace y with dy/dx, and derive everything else regularly, so, dy/dx-10x=7y^6dy/dx
solve for dy/dx
-10x=-dy/dx+7y^6dy/dx
-10x/(-1+7y^6)=dy/dx
hope that helps

Answer 4

then dy/dx the entire equation:

Answer 5

the 5x^2 becomes 10x

Answer 6

the y becomes just y' and y^7 becomes 7y^6y'.

Answer 7

then pull out a y' . so you have y'(7y^6-1)

Answer 8

wouldnt the y' become dy/dx?

Answer 9

then just move that whole parenthesis to the other side and you have your answer:)
