x³-x=x(x²-1)=x(x+1)(x-1)
First we want to calculate the derivative of y. To do this we use the product rule:If we rewrite y as y = uv, then dy/dx = vdu/dx + udv/dx.Here, we have u = x and v = cos(x).That means du/dx = 1 ...
Equation 1: 2x + y = 14 Equation 2: 4x - y = 10
Add the two equations together to get 6x = 24. Therefore x = 4.
Then substitute the value x = 4 into equation 1 and solve. ...
