Okay, so here we need to compare the same trait functions, but these two functions are different.
00:08
However, we can, we know that they're co -functions, and so we can write this function in terms of this function, and vice versa.
00:19
So let's do this one first, so co -tangent of 41 degrees.
00:23
It's the same thing as this is an acute angle.
00:25
It's less than 90 degrees.
00:27
So you can do this.
00:28
You can write this as tangent of...
00:31
90 minus 90 degrees minus 41 degrees and this should give you tangent of let's see this should be 49 degrees so this expression here should be tangent of 41 degrees in terms of co -tangent in terms of tangent looks like this so they should be less than tangent of 49 degrees so when you have the same train.

Functions it's easy to compare the values of the angles...
