Question

SinA•cosA•tanA+cosA-SinA.cotA give answer pls
​

Answer 1

Explanation:

Tan A = Sin A/Cos A

Cot A = Cos A / Sin A

Sin A*Cos A * tan A + Cos A * Sin A * Cot A

`= Sin A * Cos A * (Sin A)/(Cos A) + Cos A*Sin A * (Cos A)/(Sin A)\\\\= Sin A * Sin A + Cos A * Cos A\\\\= Sin^(2) A + Cos^(2) A\\\\= 1`
