Answer:
- sin(x) = 1
- cos(x) = 0
- cot(x) = 0
- csc(x) = 1
- sec(x) = undefined
Step-by-step explanation:
The tangent function can be considered to be the ratio of the sine and cosine functions:
tan(x) = sin(x)/cos(x)
It will be undefined where cos(x) = 0. The values of x where that occurs are odd multiples of π. The smallest such multiple is x=π/2. The value of the sine function there is positive: sin(π/2) = 1.
The corresponding trig function values are ...
tan(x) = undefined (where sin(x) >0)
sin(x) = 1
cos(x) = 0
__
And the reciprocal function values at x=π/2 are ...
cot(x) = 0 . . . . . . 1/tan(x)
csc(x) = 1 . . . . . . .1/sin(x)
sec(x) = undefined . . . . . 1/cos(x)

Step-by-step explanation:
Surface area Formula for a Cube:
The "edge", which is also the side, is 18 inches.
Solve the formula.
The cube's surface area should be 1944 square inches.
Answer:
45(1+2)
Step-by-step explanation:
Looking at you options, you can see that 45 is your Greatest common factor (GCF)
45 X 1 = 45
45 X 2 =90
45(1+2)
The exact form is -15/28 and the decimal form is -0.535
Step-by-step explanation:
-2x - 5 = 4
-2x = 9
x= -4.5
