Question

cos=a/b so sin×cot+cosec×tan​

Answer 1

Answer:

Step-by-step explanation:

SinA×cosA/sinA+1/sinA×sinA/cosA

CosA+1/cosA

A/B+B/A

A^2+B^2/AB Ans.

Answer 2

Step-by-step explanation:

if cos=a/b =b/h

therefore, by Pythagoras theorem,

sin=√a^2+b^2 /b

cot=a/ √a^2+b^2

similarly find other ratios and substitute them and you will get your ans..
