Question

how would I solve for
sec(arcsin(-7/25)) ?

Answer 1

so far me has sec(25/24) ?

Answer 2

@sourwing sorry for bothering you this much :/

Answer 3

let y = arcsin(-7/25), the what is sin(y) ?

Answer 4

idk >,< .-.

Answer 5

you just need to take sine for both sides
sin(y) = -7/25

Answer 6

oh right
then I drew triangle

Answer 7

yep :)
so sec(25/24) ?

Answer 8

no

Answer 9

sec(y) = 1/cos(y) = 1/(24/25) = 25/24

since y = arctan(-7/25)
sec(y) = sec(arctan(-7/25)) = 25/24 <--

Answer 10

you said sec(25/24) which is wrong. perhaps you meant sec(y) = 25/24 ?

Answer 11

oh right o.o
so overall then sec(arcsin(-7/25)) = 25/24?

Answer 12

yes

Answer 13

alright ^_^ thanks :)
