Answer:
cos thetha/sin thetha *1/cos thetha
1/sin thetha
which can be written as cosec thetha
Answer:
csc θ
Step-by-step explanation:
cot θ sec θ can be substituted by reducing the expression into equivalent parts.
cot θ = (cos θ)/(sin θ)
sec θ = 1/(cos θ)
Reduce these two values to get 1/(sin θ)
This expression can then be changed to csc θ, as it is also equivalent.
