In order to calculate this gradient, follow these steps: Choose any two points along your straight line Draw a right angled triangle where your straight line is the hypotenuse Calculate the change in the y co-ordinates divided by the change in the x- coordinates to find the gradient of the line Example a - Find the gradient of the following line and the equation of this line. Solution a - Firstly, choose two points of this line, for example : 5, 9 and 1,1. In order to do this you must understand how to use 't he trapezium rule '. By finding the gradient of curve, you are able to see the rate at which the curve slopes upwards or downwards. The resulting value will be the gradient of the curve at that particular point.

Differentiate algebraic and trigonometric equations, rate of change, stationary points, nature, curve sketching, and equation of tangent in Higher Maths. The derivative (or gradient function) describes the gradient of a curve at any point on the Find the equation of the tangent to the curve y=3x2 at the point (1;3). Differentiation - Revision 6 - Higher Maths - BBC Bitesize. -coordinates of 3) determine the nature of each stationary point 4) Find an equation for C with Problem 3 - Students may either place 'mirrors along the X and Y axis Problem 2 Calculus question taking derivative to find horizontal tangent line x2=−1.
However, for your GCSE Higher Tier maths paper, you will only be required to understand and solve basic pre-calculus problems concerning these topics.
Where 'n' the number of strips Example a - Use the trapezium rule to find the area under the curve:. If you intend to study AS and A Level Maths, these pre-calculus skills will be incredibly useful and will give you a solid base of knowledge upon which you can rely.
Now draw a right angled triangle where your straight line is the hypotenuse:.

Differentiation * Tangents to curves * Increasing and decreasing.
First of all, we need to differentiate the equation of the curve to get an expression for the gradient. By doing so, you are dividing the change in height of your straight line graph by the change in its horizontal distance.

|We do know, however that the answer isso we can set this equal to the differentiated expression and solve the equation to find.
Now draw a right angled triangle where your straight line is the hypotenuse:. The specific questions you will be expected to answer will vary depending upon which examination board with which you are registered, but as a rule you will be required to: Estimate the gradient of a straight line Estimate the gradient of a curve Estimate the area under a graph using the trapezium rule Listed below are a series of summaries and worked examples to help you solidify your pre-calculus skills.
Questions which require you to understand and demonstrate pre-calculus skills can often appear difficult at first. If you intend to study AS and A Level maths, you will study these mathematical fields of differentiation and integration in more depth.
