Question

How do you find csc(-3pi/4)

Answer 1

csc(-3pi/4) = 1/sin(-3pi/4) = 1/(-(sin3pi/4)) = - 1/sin3pi/4 = ...
do u know the exact value of sin(3pi/4) ?

Answer 2

sin(3pi/4) would be \[\frac{ \sqrt{2} }{ 2 }\] right because its the same as sin(pi/4)

Answer 3

3pi/4=pi-pi/4

Answer 4

would it just be the negative of the csc(3pi/4) or is that wrong. Please help

Answer 5

sin(3pi/4) = sin(pi/4) = 1/2 * sqrt(2)

Answer 6

@RadEn I got that part my question is how I would make that into csc(-3pi/4)

Answer 7

so, what is -1/(1/2 * sqrt(2)) ?

Answer 8

ok I think I got it now thanks a lot
