Here is some thoughts on this:
cos 57 = sin (90-57) = sin 33
so cos 57 . cosec 33 = cos 57 / sin 33 = sin 33 / sin33 = 1
2 cos 60 = 2 * 1/2 = 1
so the last 2 parts work out to 0
now we have to find cos 70 / sin 20
sin 20 = cos 70 so this comes to 1
so finally the answer is 1
Abraham has 6 jawbreakers.
Isaac has 13 lollipops.
Jacob has 9 peanut butter cups.
If Ahmed ... one of Rebecca's camels that can't resist candy ...
makes the rounds in the middle of the night, breaks into each
of their tents, and eats all of the patriarchs' sweets, how many
pieces of candy will Ahmed the camel eat before sunrise ?
Answer: Choice D) 
The steps to finding the inverse will have us swap x and y. Afterward, we solve for y
------------------------------
Extra info:
The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on 
to make it a one-to-one function, to make the inverse a function. One possible domain restriction is 
which would lead to the inverse function
