Question

Evaluate arccsc(sqrt 2)

Answer 1

pie/4

Answer 2

thanks :D <3

Answer 3

arccsc is inverse csc
csc takes in an angle A and outputs a 1/sin(A) for that angle, so inverse csc simply does the opposite. It takes in a number, 1/sin(A) and tells you an angle that that is true for.
1/sin(A) = sqrt 2
sin(A) = 1/sqrt(2)

For what angle is sin(A) 1/sqrt(2)?

Answer 4

45

Answer 5

Evaluate .sin( Tan^-1 0?

Answer 6

it should be series?????

Answer 7

Start inside and work out.
tan^-1(0) means what angle gives tan(A) = 0
Tan(A) mean Opposite/Adjacent = 0, so what angle has an opposite side of 0?
Once you get that angle, that is input into sin and evaluated.
