Question

prove that cot θ+ tan θ= sec θ cosec

Answer 1

Step-by-step explanation:

IN RHS

cot A+tanA

we can write this as

Cos A ÷SinA +SinA ÷CosA

so,

CosA square + sinA square

1÷sinA * Cos A

Now,

1÷sin A * 1 ÷ cos A

cosecA * secA

hence proved

* this is denoted multiply

square denote the square for theta or any thing in answer
