Question

sec square A*cosec square A-(tan square A+cot square A)​

Answer 1

Answer: 2

Explanation

we know that,

tan square A + cot sqaure A = sec sqaure A* cosec sqaure A -2

by substituting this in the equation we get,

sec sqaure A * cosec sqaure A -( sec sqaure A* cosec sqaure A -2)

= 2

hence the value of above is 2
