Find First Derivative: We are given the function y=5cos(2x+10), and we need to find the second derivative of y with respect to x, which is denoted as dx2d2y. The first step is to find the first derivative of y with respect to x. Using the chain rule, the derivative of cos(u) with respect to x is −sin(u)⋅dxdu, where u=2x+10 in this case. y0y1
Find Second Derivative: Now that we have the first derivative, we need to find the second derivative. We will differentiate −2sin(2x+10) with respect to x. Using the chain rule again, the derivative of −sin(u) with respect to x is −cos(u)⋅(dxdu), where u=2x+10. dx2d2y=−cos(2x+10)⋅dxd(2x+10)dx2d2y=−cos(2x+10)⋅2
Simplify Expression: Simplify the expression for the second derivative.(d2y)/(dx2)=−2×cos(2x+10)×2(d2y)/(dx2)=−4cos(2x+10)
