Q. For the following equation, evaluate dxdy when x=2.y=x4+5xAnswer:
Identify Problem Type: Identify the type of problem and the method to solve it. We need to find the derivative of the function y with respect to x, and then evaluate it at x=2. This is a differentiation problem.
Differentiate Function: Differentiate the function y=x4+5x with respect to x. The derivative of x4 with respect to x is 4x3, and the derivative of 5x with respect to x is 5.
Combine Derivatives: Combine the derivatives to get the expression for dxdy. The combined derivative is dxdy=4x3+5.
Evaluate at x=2: Evaluate the derivative at x=2. Substitute x=2 into the derivative to get dxdy=4(2)3+5.
Calculate Value: Calculate the value of (dxdy) when x=2. The calculation is (dxdy)=4(8)+5=32+5=37.
