It is important to remember other angles rules, such as angles on a straight line add up to 180°, and to recognise angles in parallel lines. Make sure you are confident in applying Pythagoras’ theorem ...
In this video I will cover how to evaluate the six trigonometric functions given a right triangle. We will find the missing side of the triangle using Pythagorean Theorem and then write the ratio for ...
Given a function f(x), and two points on the curve (a, f(a)) and (b, f(b)) the line joining these two points is called a secant line of f. (Not to be confused with the trigonometric secant (sec) ...
