Answer:
The answer to your question is below
Step-by-step explanation:
Data
A (4 , -3)
r = ?
sin = ?
cos = ?
tan = ?
Process
1.- Plot the point
This point is in the fourth quadrangle
2.- Calculate r
We have the Opposite side and the Adjacent side
tan Ф = -3/4
tan⁻¹ Ф = Ф = 323.1
Ф = 323.1°
3.- sinФ =
Calculate the hypotenuse
c² = 4² + (-3)²
c² = 16 + 9
c² = 25
c = 5
sinФ = -3/5
cos Ф = 4/5
tan Ф = -3/4

EXPLANATION:
We are able to use the transformation formula
f
(
x
)
=
a
⋅
cos
(
x
−
h
b
)
+
k
. You start with
f
(
x
)
=
cos
(
x
)
and replace
a
with the desired amplitude,
h
with the desired horizontal shift, and
k
with the desired vertical shift. This leaves out the
b
-value. A regular cosine function has a period of
2
π
. If you want a period of
π
, since that is one half of the original period, you need to replace your
b
with a
1
2
.
This is about how it would work out.
f

From there you simplify your equation giving you
f

)
=
