Question

please prove and give me​

Answer 1

Heya

______________________________

1 + Tan² A = Sec² A And 1 + Cot² A =

Cosec² A

Tan A = Sin A / Cos A

Cot A = Cos A / Sin A

_______________________________

Tan A / Sec⁴ A + Cot A / Cosec⁴ A

=>

Sin A × Cos³ A + Sin³ A × Cos A

=>

Sin A × Cos A { Cos² A + Sin² A }

=>

Sin A × Cos A { 1 }

=>

Sin A × Cos A
