Question

if x = cosec thetha + cot thetha and y= cosec thetha -cot thetha find the value of xy​

Answer 1

Answer:

Here's your answer

(cosec theta+cot theta)(cosec theta-cot theta)

(cosec theta²-cosec theta(cot theta) +cot theta(cos theta)+cot theta²

cosec theta²+cot theta²-Answer

Hope it will help you

Answer 2

Step-by-step explanation:

x = cosec@ + cot@

y = cosec@ - cot@

=> xy = (cosec@+cot@)*(cosec@-cot@)

=> xy = cosec²@ - cot²@

=> xy = 1
