23/08/2009 · Best Answer: Ok Let's say you have an equation Y = Cosx; In order to find the derivative, you need to know the derivatives of the trig functions which are given. Here are the derivatives for each of the Trig functions: Sinx = Cosx Cosx = -Sinx Tanx = …... It is possible to find the derivative of trigonometric functions. Here is a list of the derivatives that you need to know: d (sin x) = cos x

-A2A- I wouldn't be handing out the answer, rather I would guide you through the approach. For x=a to be an inflection point, second derivative of the function must be zero at x=a. Mathematically, f ''(a) = 0. Notice that this is a necessary co......How To How To Differentiate A Log Function, An Exponential Function And A Trig Function Using The Product Rule Applications Of Differentiation How To Find The Nature Of The Stationary Points Of An Algebraic Function Using Differentiation Concepts

## How To Find Stationary Points Of A Trig Function

### 18/05/2010 · I had to look up "stationary points." Not a common term in my math education in the U.S., but it means a point where the tangent is zero. Find the derivative: y' = cosx - sinx and set to zero to find the stationary points

- 14/01/2010 · Maths C3 problem. stationary points and trig identities? This is the question: A curve is defined for 0 < x < pi/4 by the equation y= xcos(2x). a) Find dy/dx - done this and i got -2xsin(2x) + cos(2x) = 0 b) The point a, where x = A, on the curve is a stationary point.
- As well as finding stationary points we also want to know what type they are (maximum, minimum or point of inflection). This is called finding the nature of the stationary point. In this class you'll learn how to use a nature table to demonstrate what kind of stationary point a function has.
