Using the product rule: d/dx(ab)=ab’ + a’b where a and b are variables which have been differentiated with respect to x
Derivative: 2(x^2(dy/dx)+2xy) + 2 + 4dy/dx+πsin(πy)...
This involves the product rule for counting. Step 1: Identify the possible numbers for the first digit 5, 6, 7, 8 or 9 (5 in total) Step 2: Identify the possible numbers for the second digit 2, 3, 5 or 7 ...
Step 1: Simplify the quadratic by dividing by 2. 5x2 < 32x - 12 Step 2: Move all terms onto one side of the quadratic. 5x2 - 32x + 12 < 0 Step 3: Factorise the quadratic. (5x -...
