00:01 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...
