Trigonometry is an easy way to work out the unknown sides and angles of a right angled triangle. The trick - know the side names - the opposite, hypotenuse, and adjacent, and know how and when to apply the trigonomic functions - sin, cos and tan. This is the only trick to getting it right every time!
In this lesson, students learn work out unknown side lengths using use sine, cosine, and tangent. You will need a scientific calculator for the problems in this lesson - and I'll show you how to access one on your computer.

How do you solve conditional probability examples?
What is the probability of an event A given that event B has occurred?
This is conditional probability, solved by the formula that P(A|B) which reads "probability of A given B" is equal to the P(A intersect B)/P(B).
Three examples are examined.
