Sir o to pie alaa sir

[@sanjusharma2284]

Sir please first exercise ka first question solve krke bhej do please

[@rahulsinghrajput7293]

Sir , sin ( π - x ) = sin x hota hai.

[@farasultana5080]

Sir sin(pi-x) = sinx not -sinx....????

[@TEAMEDUCATIONMATHEMATICS]

Sinx only

[@TEAMEDUCATIONMATHEMATICS]

(Pi-x) is in second quadrant

[@farasultana5080]

In the last which theorem you are applied... Plzz.... Tell the name... Something m-1/m ...

[@TEAMEDUCATIONMATHEMATICS]

Reduction formula

[@rakeshrachapudi04]

why should we subtract 2 from numerator and denominator , 🤦‍♂

[@TEAMEDUCATIONMATHEMATICS]

It is formula , definite Integration with limits zero to pi/2 sinx or cosx or sinx.cosx even for higher powers ,we are using this formula it is called wallis formula, very easy ,better search in google "wallis formula"
