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 to label sides and angles in right triangles as well as when to 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.

Vedic Maths is series of mathematical tricks, originating in a book written by an Indian monk Swami Bharati Krishna Tirtha in 1965. It contained a list of mental calculation techniques which were claimed to be retrieved from the Vedas - are a large body of religious texts originating in ancient India.
Please if you are learning this, however, do not treat multiplication as a mere trick. It is important to remember 17 x 13 for example, is the repeated adding of 17, 13 times (17 + 17 + 17 + 17...).
This method is a shortcut, but as the end proof shows, it is using a shuffling of required calculations to make this multiplication more efficient.
For 17 x 13, we have lots of multiplication going on (that is repeated addition!) - 10 x 10 and 3 x 10 and 7 x 10 (lots of 10s - 20 all up) - and 7 x 3.

In this lesson, you will learn to multiply fractions quickly and easily.
To multiply fractions you multiply across the numerators (the top number of a fraction) and multiply across the denominators (the bottom number).
An example I always use to start this off is multiply 1/2 with a 1/2. The numerators multiply to give 1 (1 x1), the denominators multiply to give 4 (2x2). Hence a 1/2 multiplied by a 1/2 is 1/4.
What about if you multiply 2/3x1/4?
Top number (2x1), bottom number (3x4).
So 2/3x1/4 = 2/12. To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU To donate to the tecmath channel: https://paypal.me/tecmath?locale.x=en_AU
