Answer»

EXPLANATION.

  • GIVEN

5) = m = cosecø + cotø

n = cosecø - cotø

PROVE THAT MN = 1.

put the VALUE of m and n

( cosecø + cotø) ( cosecø - cotø)

it is in form of (a + B ) ( a - b) = a^2 - b^2

( cosec^2ø - cot^2ø ) = 1

Hence,proved

6) = m = secø + tanø

n = secø - tanø

PROVE THAT MN = 1.

put the value of m and n

( secø + tanø) ( secø - tanø)

it is in form of ( a - b) ( a + b) = a^2 - b^2

( sec^2ø - tan^2ø ) = 1

Hence,proved
