Given , what is the value of ?

Given,

tan θ = 1/√5

In ∆ ABC,

AC² = AB² + BC²

AC² = 1² + (√5)²

AC² = 1 + 5 = 6

AC = √6

We have,

cosec θ = AC/AB = √6/1

sec θ = AC/BC = √6/√5

Now,

If , find the value of

If 3cot θ = 4, find the value of

If, rite the value of

If tan A = 3/4 and A + B = 90°, then what is the value of cot B ?
