The inverse trig functions

The inverse trig functions only exist when we restrict the domain of the original functions. So that they become 1:1 mappings

Change of Sign Methods

To find the root of a function f(x), if

f(a) > 0f(b) < 0

and the function is continuous, then there is a root between a and b.

We can narrow this down by successively halving the size of the interval, until we get an answer to the required accuracy.

Example

6.1 Numerical Methods

We can continue this method indefinitely, to whatever accuracy we require

This method is useful for confirming the existence of a root between two given values. It can be unreliable however, sometimes failing to find a

root(s) when they are very close together, or ‘finding’ a root that doesn’t exist.

Iterative Methods

(there are many other re-arrangements you could have done)

Then start at any value (it will be given in the question; here we use x=0, and show 3 iterations)

This method continues until it converges on the solution x = 0.276 (to 3 dp)

Iterative methods will often fail to find the root for given re-arrangements. If this is the case, you must try a different re-arrangement.

In this example, yn = y8
