In this question, we are given the sign of an angle and its quadrant.
00:08
We will find the other five trig values.
00:15
The angle we are working with, we are told, is in quadrant two.
00:26
Sign and its reciprocal are positive.
00:31
In quadrant two, everything else is negative.
00:35
So if we're told that sine of theta is three -fourths, the easiest trig function to find is co -seacant because it's the reciprocal.
01:00
Next, let's find cosine.
01:05
Sign squared of theta plus cosine squared of theta is one.
01:13
Sign is three -fourths.
01:24
Three -fourths squared is nine -sixteenths.
01:30
I'm going to subtract that from one...
