Question

anyone explain this sol. please​

Answer 1

$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

LHS

⟹ $\mathtt{sin\:A (1+\frac{sin\:A}{cos\:A})+cos\:A(1+\frac{cos\:A}{sin\:A})}$

Iss step me unhone bracet vaale 1/cos A ka 1 ke saath LCM le liya or right side me sin A ka bhi 1 ke saath LCM liya haii.. So ye kuch aisa bnn gyaa

⟹ $\mathtt{\frac{sin\:A(cos\:A+sin\:A}{cos\:A}+\frac{cos\:A(sin\:A+cos\:A}{sin\:A}}$

____________________

• Abb iss step me unhone Common liya hai..

• Common kaise lete haii ..

• Hamesha do eqn ko jodne vaale plus that is beech vaale plus sign ke left side and right side se common liya jaata haii ...

• Pehle dekha jaata haii common ke left or right side me konsi term similar hai or fir common lete haii

____________________

Isme left or right side numerator me ( sin A + cos A ) common hai toh isme vo common liya gya haii.. or ye step iss question kaa sbse mushkil step lgta hai bacho koo..

⟹ $\mathtt{(sin\:A+cos\:A)(\frac{sin\:A}{cos\:a}+\frac{cos\:A}{sin\:A})}$

Abb simply (sin A/cos A + cos A/sin A ) ka lcm liya hai or bracket khola haii..

Or aage question simply solve krr dete haii agar aage question me bhi koi problem ko mere question me answer krke puuch liyoo..
