Today's lesson was on derivatives of inverse trigonometric functions. Tutorial videos below, can you try questions from this section? We have completed Differentiation 1 (although we will look at 1st principles later in more detail).

Next week we will have our summer assessments with questions from the following 4 chapters:

The Line
The Circle
Trigonometry 1

Differentiation Section 4
Differentiation by Rule: Powers and Polynomial Functions

The following 5 tutorial videos should enable you to attempt all questions in Section 7.

Note: There are two notations used for the derivative of a function "dy/dx" and "f'(x)" there is no difference in the meaning of these, "dy/dx" tends to be used if the function to be differentiated is expressed in terms of "y=" and "f'(x)" if the function is expressed as "f(x)=" as you will see in the tutorials.
