Question

are sin (-x) and sin - x the same? I mean, when you graph them, are they the same? thanks

Answer 1

sin(-x) is an expression that makes sense. What is sin - x?

Answer 2

uhm, basically its part of a piecewise function given here.

Answer 3

in order for sin - x to make sense, there has to exist an angular value or expression within the parentheses.

Answer 4

sin(?)

Answer 5

oh. wait. ive got my equation here. :)

Answer 6

Okay, so it's just sin(-x)

Answer 7

its a piecewise function as you can see :)

i just dont know how to graph the first equation. haha

Answer 8

so sin - x is equal to sin (-x) then? :)

Answer 9

There's no such thing as sin - x

Answer 10

don't worry yourself about it

Answer 11

sometimes you see expressions where they write sin x without the parentheses. It's just shorthand...the parentheses are implied but they still exist.

Answer 12

sin x is the same as sin(x)

Answer 13

Just like x = 1x

Answer 14

1 times x is implied, but writing x alone is just shorthand

Answer 15

ohh, okaaay. :)

Answer 16

thanks for letting me understand. :)
