Write the expression cot? A+tanº A-csc? 8+2 as a single term. -sec 6
B.
sec 6
C. secé
0.-cos? 6

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

answer: 1475

step-by-step explanation:

becuase you have to know what they are asking you

thus, the first answer choice, y = sec x, is the correct one

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
