Question

Find the exact value of csc(300∘) using the 3 step process discussed in the lecture notes. 

1.) Find the reference angle (degrees):    .

2.) Apply the trig function to the reference angle:  csc(____) = (____)

3.) Apply the appropriate sign: csc(300°) = ___   Do not use decimals.

Answer 1

csc300 = csc(-60) = 1/sin(-60) = -1/sin60 = -2/sqr3
