Question

Tan^2 theata -sec^2 theata

Answer 1

Answer:

LHS:=tan^2theata+cos^2theata+2

• sec^2theata-1+cosec^2-1+2
• sec^2theata+cosec^2theata
• 1/cos^2theata+1/sin^2theata
• sin^2theata+cos^2theata/sin^2..cos^2theata
• 1/sin^2theata..cos^2theata
• 1/sin^2theata 1/cos^2theata
• =cos^2theata..sec^2theata

hope this will help u!
