⭐⭐⭐⭐⭐ ANSWER ⭐⭐⭐⭐⭐
==================================
- since it is given that 3x=cosec theta and 3/x=cot theta
- so,x=cosec theta/3 & 1/x=cot theta/3
- so,3(cosec theta^2/9 - cot^2/9)
- 3[1/9(cosec theta^2 - cot theta^2). -(1)
- as we know that 1 + cot theta^2=cosec theta^2
- 1=cosec theta^2 - cot theta ^2. -(2)
- putting value of (2) in (1)
- 1/3(1)
- 1/3
- I would suggest u to first WRITE the given solution in copy as given for better clearance of your doubts and if not understood then type it.
2.okk so NexT is This...
- secA = 2x -----( 1 )
- tanA = 2/x ------( 2 )
- sec² A - tan² A = 1
- ( 2x )² - ( 2 /x )² = 1
- 4x² - 4/x² = 1
- 4 ( x² - 1/ x² ) = 1
- 2( x² - 1/ x² ) = 1/2
- I hope this helps you.
