ECZ 2024 · GCE Paper 2 · Question 5 — Introduction To Calculus
A flowchart is given (see diagram): Start; Enter r, θ; Is r < 0? Yes: Print 'error, r is not valid'; No: A = (θ/360)*π*r2; Print A; Stop.
(a) Evaluate the integral of (6x5 - x4 + 3x2 - 1) dx from x = -1 to x = 2.[3]
Verified working — step 1
∫(6x5 - x4 + 3x2 - 1) dx = x6 - x5/5 + x3 - x + C(b) Write a pseudocode corresponding to the flowchart program above.[5]
