Question

pls answer this I will mark as BRAINLIEST..... ​

Answer 1

Answer:

m = (cos∅ - sin∅)

n = (cos∅ + sin∅)

LHS=

n

m

+

m

n

=

n

m

+

m

n

=

mn

m+n

now, put m =( cos∅ - sin∅) and n = (cos∅ + sin∅)

= {(cos∅ - sin∅)+(cos∅ + sin∅)}/√{cos∅-sin∅)(cos∅+sin∅)}

= 2cos∅/√{cos²∅ - sin²∅}

= 2/√{cos²∅/cos²∅ - sin²∅/cos²∅}

= 2/√{1 - tan²∅} = RHS
