Q. Let y be defined implicitly by the equation6x3+y8=10. Use implicit differentiation to find dxdy.
Differentiate 6x3: To find the derivative dxdy using implicit differentiation, we need to differentiate both sides of the equation with respect to x. The equation is 6x3+y8=10.
Differentiate y8: Differentiate 6x3 with respect to x. The derivative of 6x3 with respect to x is 18x2.
Differentiate 10: Differentiate y8 with respect to x. Since y is a function of x, we need to use the chain rule. The derivative of y8 with respect to x is −y28∗dxdy.
Combine derivatives: Differentiate 10 with respect to x. The derivative of a constant is 0.
Solve for dxdy: Combine the derivatives from the previous steps to form the differentiated equation: 18x2−y28⋅dxdy=0.
Simplify dxdy: Solve for dxdy. To do this, we isolate dxdy on one side of the equation. We get dxdy=818x2⋅y2.
Simplify dxdy: Solve for dxdy. To do this, we isolate dxdy on one side of the equation. We get dxdy=818x2⋅y2.Simplify the expression for dxdy. We can simplify 818x2⋅y2 to 49x2⋅y2.
