Question

cosec 65° - sec 25° + tana 30° - cot? 60° is;​

Answer 1

Answer:

0

Step-by-step explanation:

cosec 65° - sec 25° + tan 30° - cot 60°

= $\frac{1}{sin 65} -\frac{1}{cos 25} + \frac{1}{\sqrt{3} } - \frac{1}{\sqrt{3} }$       ∵ $tan30=\frac{1}{\sqrt{3} }$  and $cot60=\frac{1}{\sqrt{3} }$

= $\frac{1}{cos(90-65)} - \frac{1}{cos 25}$    ∵sinθ = cos(90-θ)

= 0
