Final answer:

Using the given value of sin(B) = 4/13 and the formulas for cosec, cos, tan, sec, and cot, the exact values of the remaining trig functions for angle B are:

1) cosec(B) = 13/4

2) cos(B) = ±√(3/13)

3) tan(B) = (4√3)/3

4) sec(B) = (√39)/3

5) cot(B) = (√3)/4

Step-by-step explanation:

To find the exact values of the remaining trig functions for angle B, given that sin(B) = 4/13, we can use the following formulas:

cosec(B) = 1/sin(B)

cos(B) = ±√(1 - sin^2(B))

tan(B) = sin(B)/cos(B)

sec(B) = 1/cos(B)

cot(B) = 1/tan(B)

Let's substitute the given value of sin(B) = 4/13 into these formulas:

1) cosec(B) = 1/(4/13)

= 13/4

2) cos(B) = ±√(1 - (4/13)^2)

= ±√(1 - 16/169)

= ±√(153/169)

= ±√(3/13)

3) tan(B) = (4/13)/(±√(3/13))

= 4/√3

= (4√3)/3

4) sec(B) = 1/(±√(3/13))

= √(13/3)

= (√13)/√3

= (√39)/3

5) cot(B) = 1/tan(B)

= 3/(4√3)

= (√3)/4
