Differentiate equation
dy/dx=0.5*x-0.5
Gradient is the same as the second equation
2/3=0..5*x-0.5
Solving this ...
(2+3√2, 0) and (2-3√2, 0)
(3*4)(4x+9)^(3-1)
Where 4 is the derivative of inside the brackets and 3 is the power of the brackets.
Therefore the answer is 12(4x+9)^2
(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...
