Question

solve the equation with the restrictions of -180< x < 90 degrees..
2 csc x =6
i have trouble doing the csc,cot and sec.. how do i plug this into my calculator csc x= 3

Answer 1

so start by solving for

csc(x) = 3

then take the reciprocal

csc = 1/sin

so

taking the reciprocal will give

sin(x) = 1/3

\[x = \sin^{-1}(\frac{1}{3})\]

since you value for csc is positive

sin will be positive

and this only occurs in the 1st quadrant...

using toe information to find x is all you need.

Answer 2

okay thanks!
