- 1Differentiationy=bx^q
dy/dx=bqx^q-1 - 2How to get to d2y/dx2Differentiate twice
- 3What does dy/dx tell you?Tells you the gradient of y
- 4How do you find a stationary pointmake dy/dx equal zero
- 5How to find the nature of a stationary point?- d2y/dx2
positive is a minimum
negative is a minimum
equal zero is a point of inflection - 6How to integratebx^q+1
-------------
q+! - 7What to use integration for?For the area under a curve
- 8What is: f'(x) f''(x)Dy/dx
d2y/dx2 - 9How to find the gradient at a certain pointdy/dx
substitute in the x value - 10First principlesThis uses the delta system. You need to chance all Y values into the y= equation. Ensure all values are X and XDelta.
- 11How to find the area under a curve with integration?1. Integrate but ignore the c
2. Substitute the lower and upper values
3. Subtract them
4. A negative answer just means they are underneath the x axis - make it positive. - 12How to use the trapezium rule? What is the problem with the trapezium rule?They will say the number of strips or ordinates (N strips = N+1 ordinates)
The height is the width of the strip.
2* the middle ordinates and 1* the outer ordinates.
-----
It is a lot less accurate and is only an approx. value
