Sin A(1+ sin A/cos A) +cosA + (1+cos A/sin A)
= sin A(sinA+cosA/cosA) + cosA(cosA+sinA)
= sinA+cosA([sinA/cosA] +[cos A/sin A]
= sin A+cosA (sin2A+cos2A) /sin. Cos
= sin + cos /sin. cos
= sin/sin. cos+ cos/sin. cos
= 1/cos+1/sin
= secA+cosecA.
= sin A(sinA+cosA/cosA) + cosA(cosA+sinA)
= sinA+cosA([sinA/cosA] +[cos A/sin A]
= sin A+cosA (sin2A+cos2A) /sin. Cos
= sin + cos /sin. cos
= sin/sin. cos+ cos/sin. cos
= 1/cos+1/sin
= secA+cosecA.
This question is thoda sa tough hai.
