Answer:
a) -tan(π/4) = -1
b) -1/sin(π/3) = -(2/3)√3
Step-by-step explanation:
The given functions are reciprocals of the primary trig functions:
cot(x) = 1/tan(x)
csc(x) = 1/sin(x)
The tangent function has a period of π, and is equal to the cotangent of the complementary angle.

<h3>a)</h3>
The given angle is an alias of -π/4, so we can write ...
cot(7π/4) = cot(-π/4) = -cot(π/4) = -tan(π/2 -π/4) = -tan(π/4)
-tan(π/4) = -1
__
<h3>b)</h3>
csc(-π/3) = 1/sin(-π/3) = -1/sin(π/3) = -1/(√3/2) = -2/√3
-1/sin(π/3) = -2√3/3
Answer:
Do you mean 2x<2 or
X <2 or do you mean x²<2
Step-by-step explanation:
If your question is X²<2
Then
Total outcomes=5
Possible outcomes=3(-1,0,1)
Probability of x²<2=3/5
If your question means probability of2x<2
Then
Total outcomes=5
Possible outcomes=3 (-2,-1,0)
Probability of 2x<2=3/5
If your question means x< 2
Then
Total outcomes=5
Possible outcomes=4 (-2,-1,0,1)
Probability of x <2 =4/5
