Question

TRUE or FALSE!

The notation arcsin x represents the inverse function to sine.

***My answer: TRUE!

is that right??

Answer 1

correct :)

Answer 2

yay! Thanks :)

Answer 3

you can continue asking here,

Answer 4

okay!! here's another true or false :)

Answer 5

why you say false ?

Answer 6

cuz there's an infinite number of angles right?? but not values right? cuz sin^-1 is has the limited range of -pi/2 to pi/2 right?? am i getting that right? :)

Answer 7

not actually,
arcsin does not have limited range unless specified specially.
the value of that expression is an angle.

Answer 8

ohhh :( darn.. so does that make this sentence TRUE then?

Answer 9

i looked up wiki, seems i was incorrect :P
the ranges are restricted in order to have inverse functions.
you were correct.

Answer 10

sorry, its false only.

Answer 11

awesome!! so it is FALSE then? :)

Answer 12

cool!! :) hehe one sec while i post the next one!

Answer 13

The attached graph depicts which inverse trigonometric function?

A. y=Arcsin x

B. y=Arccos x

C. y=Arctan x

D. y=Arcsec x

**my answer: B. y=Arccos x

not too sure tho... is that right?? am i remembering the graphs correctly? ;/

Answer 14

what do u think @hartnn ? :)

Answer 15

yes, its arccos x

Answer 16

woooo!! :) yayy!! lemme put the next one up!! it's a another true or false... one sec!!
