6 csc -1 = 5 Solve the equation on the interval [0,2). Write answer from least to greatest.

2cos+23= 3 Solve the equation on the interval [0,2). Write answer in set notation from least to greatest.

Solution

6 csc -1 = 5

6 csc = 5 +1

6 csc =6

csc = 1

= {/2}

==================================

2cos+23= 3

2cos= 3 -23

2cos= -3

cos= -(3)/2

={5/6,7/6}
