6. About Closed Intervals

  • This is when a restriction is placed on the Domain
  • In this restriction the max/min values can occur at the SP’s or at the end points
  • Find max/min values (y) of the end points by substituting both x values into the equation
  • Differentiation and a nature table is required to find the stationary points
  • A sketch showing the end points and SP’s may be asked for in Higher exam questions

.

To sketch a curve

  • Determine the x-axis intercepts (roots)           ⇒ put y = 0 and solve for x
  • Determine the y-axis intercepts                       ⇒ put x = 0 and solve for y
  • Determine the turning points and their nature ⇒ use a nature table
  • Find the end points ⇒ sub both the x values of the end points into the equation to find y

.                                     

Resources on Differentiation can be found;

  • My daughter says the Higher website was really helpful. She achieved an ‘A’ for Higher Maths this year and is now undertaking Advanced Higher Maths for which she would like me to subscribe to your AH website . I shall go and do that now –  Thanks again.

    Mrs Gove – November 2018

  • Just wanted to say thanks for providing the great higher maths material. I am pleased to say I got an A in my higher maths course.
    Your material really helped me focus my study efforts for the exam.

    Mike – August 2018

  • Just a HUGE thank you from me – I’ve been teaching Higher Maths for about 20 years and your site has made this so much easier. Having topic by topic past paper questions, HSN notes and SQA papers all on one site is wonderful. So easy just to direct students to your amazing site! – Thank you.

    Karen – March 2018

  • Firstly, I wanted to say the materials on the new website are great.

    I have just had my Prelim at Fife College for my Higher Maths evening class. It has highlighted the need to do loads of past papers before the exam. I found the worked solutions provided for the past papers in the Online Study Pack so much more helpful than the marking schemes.

    Mike – March 2018

  • The Higher Maths website is great – only £9.99 is such good value for what you get. I am feeling a lot more confident for the exam now!
