Q. Find the derivative of the following function.y=e−6x6+3x5Answer: y′=
Identify function: Identify the function to differentiate.y=e(−6x6+3x5)This is an exponential function with a composite function as the exponent.
Apply chain rule: Apply the chain rule for differentiation, which states that the derivative of a composite function is the derivative of the outer function evaluated at the inner function times the derivative of the inner function.Let u(x)=−6x6+3x5 be the inner function.The outer function is eu.
Differentiate outer function: Differentiate the outer function with respect to u. If v=eu, then v′=eu⋅dxdu.
Differentiate inner function: Differentiate the inner function u(x)=−6x6+3x5 with respect to x. u′(x)=dxd(−6x6)+dxd(3x5) u′(x)=−36x5+15x4
Combine derivatives: Combine the derivatives using the chain rule.y′=v′⋅u′(x)y′=eu⋅(−36x5+15x4)Substitute u back into the equation.y′=e(−6x6+3x5)⋅(−36x5+15x4)
