central skewed right left difference for 4th order approximation using 2nd order derivative

Objective: Central differencing: For Central difference the stencil has 5 nodes, they are i-2,i-1,i,i+1,i+2. For Central difference, we r having the formula to calculate the nodes. no. of nodes = p+q-1 = 2+4-1 = 5. Here p = order of derivative …
