A particle is moving along the x-axis. Its displacement x metres from the origin after t seconds, is given by x= e^t - 2e^2t for 0 is less than equal to t or t is less than or equal to 2 (greater than or less than equal to) i) Find the initial velocity of the particle ii) Explain why the...

Having a problem with Q25 part b) I'll provide the whole question below. 'A ball is thrown up with a velocity of 15ms^-1 at an angle of 60 degrees. At the same time, another ball is thrown towards the first one, at an angle of 45 degrees and a velocity of 20ms^-1. The two balls are 30m...

I received a Band 6, for my exam I did last week, which equated to a 41/45. I received 7/10 for multiple choice and 34/35 for Short answer responses. How can I access more difficult multiple choice to improve on it, to strengthen my band 6? The difference between first (I) and second is 7...

Q12) The variable point P(2ap, ap^2) lies on x^2=4ay, and the chord OQ is drawn parallel to the tangent at P. The tangents at P and Q meet at R. C) Show that the coordinates of Q are (4ap,4ap^2) Equation of Tangent at P: y=px-ap^2 Equation of Chord OQ: y=px

So I have the question; Find the exact area enclosed between the curve y= sqrt (4-x^2) and the line x-y+2=0 At the moment, I know I can integrate it using integration by substitution and trig identities, along with inverse sin. Is there a faster or simpler way to integrate it? Thanks

Hi, I did the Ext 1 paper today for Prelim, and wow I found it very difficult along with the four other people in my class. We had been given a couple of past papers in previous years from Western Mathematics for 2013 and 2011 and this one was no where close to this one. Three quarters of...

Hey guys and girls, Currently doing Maths Ext 1 Prelim course. Have an exam this week, and have a feeling on the polynomials, I will be assessed on the quartic equation. Here is the question, I am having an issue on finding alpha beta gamma in part c of the question, as I don't believe...
