You can
put this solution on YOUR website! Write the equation sin(y) = x in the form of an inverse function.
Thank you
The equation in words would be
"The sine of y is x"
That sentence can be written this way:
"y is what we must take the sine of to get x"
The mathematical symbol for the words
"what we must take the sine of to get"
is
sin-1
That is not really a "negative one exponent", it's
only written that way because a negative
one exponent is what inverts a fraction, and that
reminds us that we are writing another kind of
inverse somewhat analogous to that, but far from
meaning that.
So from the beginning:
sin(y) = x
translates as
"The sine of y is x"
which translates as
"y is what we have to take the sine of to get x"
which translates as
y = sin-1(x)
