The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.
From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x
We can further deduce that
tan(Θ) =

sec(Θ) =

=

cosec(Θ) =

=

cot(Θ) =

=
There is no solution and it’s true
The answer is 9bt if you gave me the rest of the question I would maybe be able to get the real answer.
The function
is one-to-one and the inverse of
is
.
A function is one-to-one if for
, we show that
.
Take
Let
and
If
, then
.
So,
.
So, the function is one-to-one.
For the inverse of
, replace
with
and solve for
.
So, the inverse of
is
.

Suppose the width is w
Then the length will be w+4
Perimeter will be 2 (length + width) = 2 (w + w + 4 ) = 60
Solve this for w. Knowing w you can find the length and width.
