Answer:
While determining the angle 
with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other.
Step-by-step explanation:
See the diagram attached.
Let us assume a right triangle Δ ABC with ∠ B = 90°. Now, assume that the angle ∠ CAB = and the sides AB, BC, CA are 3, 4, 5 units respectively.
The tangent ratio of an angle is given by
Again, the cotangent ratio of angle is given by
Therefore, in both the cases of tangent ratio and cotangent ratio are inverse of each other and while determining the angle with the tangent ratio or cotangent ratio uses the same sides lengths but the ratios are inverse of each other. (Answer)

Answer:
Step-by-step explanation:
Required to prove that:
Sin θ(Sec θ + Cosec θ)= tan θ+1
Steps:
Recall sec θ= 1/cos θ and cosec θ=1/sin θ
Substitution into the Left Hand Side gives:
Sin θ(Sec θ + Cosec θ)
= Sin θ(1/cos θ + 1/sinθ )
Expanding the Brackets
=sinθ/cos θ + sinθ/sinθ
=tanθ+1 which is the Right Hand Side as required.
Note that from trigonometry sinθ/cosθ = tan θ
