Okay, so for this question, in order to figure out the given expression, we are first going to write out our expression, which is sine of pi over 3, tangent of pi over 6, plus cosecant of pi over 4.
00:27
And all of this is squared.
00:30
Now in order to solve it, we are first going to convert the radians into degrees, because having in degrees will allow us to know what number we are working with in order to solve our trick function.
00:46
So since pi is 180, pi over 3 is equal to 60, pi over 6 is equal to 30, and pi over 4 is 45.
01:04
Now we do this only if we are unsure and we haven't memorized it.
01:08
So now, since we have that, we can see that we are going to be needing our special right triangles.
01:15
Or if we are using our special right triangles if we don't have the triangles memorized.
01:22
So now we have 30, 60 here, and then 45, 45 here.
01:31
So the ones for 45 -4590, we are going to write 1, 1, and square of 2 because those are where those values are placed for any triangle with these angles...
