Once the Evidence has been uploaded the Solution Entry will automatically be available where you will select either A B C or D. Consider the equation cosh(xy") = n(e*y) " Determine an expression for y'= dy (your expression will contain both x and y dx functions). Use your calculations to answer questions 1 to 5 below. 1. The derivative with regards to x of cosh(xy") simplifies to: 2 2. What rule must you first apply to In(e*y) before differentiating it? 2 3. The simplified version of the derivative of In(e*y) is: 2 dy 4.
