I have to solve the following problem.
00:02
I need to determine functions of angle a.
00:05
Let's make this sketch.
00:06
Here, let's show the sides of the triangle, which are 3, 4, 30, and 16.
00:12
And now i'll show angle a.
00:15
Let's start with tangent a.
00:17
Tangent a is 16, or actually that is cb over ab, which is 16 over 13.
00:33
Hands, sorry, 16 over 30, hence that's letter b.
00:39
Now let's move on to that two...
