Answer:
let tana = x
cota = 1/x
now,
x²+1/x² = 17/4
adding 2 both sides we get,
x²+1/x² +2 = 17/4 + 2
(x+1/x)² = 25/4
x+1/x = 5/2
so,
tana+1/cota = 5/2 (Ans)

The value of tanθ + cotθ would be equal to 5/2.
Given:
tan²θ + cot²θ = 17/4
To Find:
The value of tanθ + cotθ
Solution:
Let tan θ = x therefore cot θ = 1/x
∵ tan²θ + cot²θ = 17/4
→ Now adding 2 on both sides to make a whole square term on the L.H.S.
∴ tanθ + cotθ = 5/2.
Hence the value of tanθ + cotθ comes out to be equal to 5/2.
