00:00:00.000 --> 00:00:05.280
There is an easy way to remember what the sine and the cosine and the tangent are.
00:00:05.280 --> 00:00:07.280
Draw a triangle.
00:00:07.280 --> 00:00:08.700
And pick an angle.
00:00:08.700 --> 00:00:10.200
Then, there are 3 sides.
00:00:10.200 --> 00:00:12.200
There is the side opposite
00:00:12.200 --> 00:00:14.200
the angle.
00:00:14.200 --> 00:00:18.200
So, if you are at the angle then you are looking
00:00:18.200 --> 00:00:20.200
you see the side opposite it.
00:00:20.200 --> 00:00:22.700
The side touching the angle.
00:00:24.200 --> 00:00:26.200
Which is the adjacent side.
00:00:26.200 --> 00:00:28.900
We will write that out in case you forget what it stands for.
00:00:28.900 --> 00:00:31.900
And, then you have the hypotenuse.
00:00:35.200 --> 00:00:37.200
And, yes these are both adjacent.
00:00:37.200 --> 00:00:39.900
But, we call this adjacent and we call that hypotenuse.
00:00:39.900 --> 00:00:41.900
And, an easy way to remember these
00:00:41.900 --> 00:00:45.500
is by a mnemonic: SOH CAH TOA.
00:00:46.500 --> 00:00:48.500
SOH CAH TOA helps you remember
00:00:48.500 --> 00:00:50.500
what the sine, cosine, and tangent are.
00:00:50.500 --> 00:00:52.500
And it stands for the
00:00:52.500 --> 00:00:54.500
sine of the angle is the
00:00:54.500 --> 00:00:58.000
opposite over the hypotenuse.
00:00:58.500 --> 00:01:00.500
The cosine
00:01:00.500 --> 00:01:03.500
is the adjacent over the hypotenuse.
00:01:04.500 --> 00:01:06.500
And the tangent
00:01:08.000 --> 00:01:10.000
is the opposite
00:01:10.000 --> 00:01:12.000
over the adjacent.
00:01:12.000 --> 00:01:14.000
