Find the acceleration of the particle when t = 3.; Sketch the velocity-time graph for 0 ≤ t ≤ 4. v = 6 – 5e-(t/3). AS Introduction. FREE Maths revision notes on the topic: COMPLETING THE SQUARE. We demand the highest levels of support for our students, with our tutors answering questions by telephone and email as required. This gives 2x+3=0, we then rearrange to get 2x=-3 and so x=-3/2. I have over 3 years of experience teaching Physics at FET level (i.e Grade 10-12). General The mark scheme for each question shows: Please answer the following questions so that a customer service representative can start your search for perfect tutor.

(3) The line through P parallel to the x-axis cuts the y-axis at the point N. The region R is bounded by C, the y-axis and PN, as shown shaded in the diagram above. You can now study with expert academics year-round. By 1999, Turning Point had 200+ students and produced excellent result with more than 70 distinctions. Therefore the coordinates of the turning point are (-3/2,19/4). Private Maths Tutor Grade 8-12(CAPS), Form 1 to 6(Cambridge/Zimsec) I have 15 years high school teaching experience in Maths, Physics, Chemistry and Biology(Life science), IT and Computer Science up to grade 12 and Advanced Level Cambridge. Physics 7408/3BD PAPER 3 SECTION B – Turning points in physics Mark scheme June 2017 . If a tangent is drawn at a turning point it will be a horizontal line; Horizontal lines have a gradient of zero; This means at a turning point the derived function (aka gradient function or derivative) equals zero Revise GCSE/IGCSEs and A-levels! This gives 2x+3=0, we then rearrange to get 2x=-3 and so x=-3/2. (b) Use calculus to find the exact area of R. (6) (Total 9 marks) The current strength has exceeded 1000+ students. Hence, we differentiate this curve. 5.1 5.2 (1) (4) (2) (2) (2) (3) (3) (5) [22] The sketch below shows the graphs of f (x) = x2 — 2x — A and B are the x-intercepts of f!
