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
For the first one, its 86 square in, and the second one is 45 square cm.
Answer:
The answer is x=2-(y/2)
Step-by-step explanation:
The answer to your question is B
Two prime numbers greater than 25 and less than 35.
Let p be a prime that satisfies
25 ≤ p ≤ 35.
The set of prime numbers:
P = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, ... }
There are only two prime numbers greater than 25 and less than 35:
Answer: {29, 31}.
