Since sine and cosecant are reciprocals, when one has a maximum the other has a minimum and vice versa.
That's choices B & D
Not sure what the question at the end is asking; at 90 degrees and also at -90 degrees the values of sine and cosecant are equal.
Answer: 21 & 18
Step-by-step explanation:
Sum of two numbers is 39
Difference is 3
Let the numbers be x & y
X+y=39........equation 1
X-y=3...........equation 2
X=3+y............equation 3
Substitute equation 3 into equation 1
(3+y)+y=39
3+y+y=39
3+2y=39
2y=39-3
2y=36
Y=36/2
Y=18
Substitute for y in equation 2
X-y=3
X-18=3
X=3+18
X=21
The two numbers are 21 & 18
The fractions 25/100 and 50/200 are both equivalent to 1/4.
