For this problem, we are going to find the solution of this expression.
00:06
So we have secant 35, co -secant 55 minus tangent 35, co -tangent 55.
00:13
So the first thing we're going to do is secant and co -secant.
00:18
Those are complementary angles.
00:21
So we're going to find the co -function.
00:27
So we have secant 35.
00:31
And then for the co -function of that, it's going to be co -secant 90 degrees.
00:36
Minus that 35.
00:40
So we're going to have secant -35 equal to co -secant, and then 90 -minus 35, that's going to give us that 55.
00:51
So we're going to substitute this co -seant -fifety -five with that secant -35 in the front...
