I'm stuck on these last two problems of my HW assignment. Any help is appreciated. Thanks.
Looking at the format, I don't think its ok to give you the answers to this, but here is some hints to help you:
For question 5, determine the value of angle t first, then substitute it in for each of the questions.
For question 6, Same as question 5. Also, consider which quadrant where sec and cosec are both positive.
