Simplify:
This is now of the form
where a=23.75 and b=76.24
<h3><u>Answer</u> :</h3>
For triangle : A + B + C = π
⇒ A + B = π - C
⇒ cot(A + B) = cot(π - C)
⇒
⇒
<u>Now 1st part of the given expression</u>!
⇒
⇒
⇒
⇒ 1 - cotB cotC
<u>Similarly 2nd part</u>!
⇒ 1 - cotA cotB
<u>Similarly 3rd part</u>!
⇒ 1 - cotC cotA
<u>LHS</u> :
= <u>RHS</u>
