Question

if cosec theta + cot theta = m, Cosec theta- cot theta =n. then find mn​

Answer 1

Answer:

hey here is your answer

pls mark it as brainliest

Step-by-step explanation:

$so \: here \: given \: trigonometric \: equations \: are \\ cosec theta + cot theta = m \\ Cosec theta- cot theta =n$

$so \: thus \: multiplying \: each \: other \: \\ we \: get \\ (cosec \: theta + cot \: theta)(cosec \: theta - cot \: theta) \\ = cosec \: square \: theta - cot \: square \: theta \\ = 1 \\ \\ since \:1 + cot \: square = cosec \: square$

$hence \: value \: of \: mn \: is \: 1$
