(a) For part a, simply add the real terms together and the imaginary terms together. z1+z2 = (3+2i)+(4-i) = 7+i b).
(b) For part b, multiply the brackets out, remembering...
First you have to identify the equation for y is a product. Then you can apply the product rule using (4x+1)^3 as one term and sin2x as the other. First you differentiate (4x+1)^3 using the chain rule. Yo...
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)...
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 -...
a) ask student: purpose of differentiation (i), how to perform differentiation (ii) (i) to find the gradient of a curve (ii) multiply the coefficient of x by its indice then minus one from the indici perf...
