Question

If sec teta + tan teta =1 then value of sec teta​

Answer 1

HEY FRIEND HERE IS YOUR ANSWER:

Given =>

SecΘ + TanΘ = 1

squaring both sides,

Sec²Θ + Tan²Θ + 2TanΘSecΘ = 1

Using identity 1 + Tan²Θ =  Sec²Θ

1 + Tan²Θ + Tan²Θ + 2TanΘSecΘ = 1

2TanΘ² = -2SecΘTanΘ

therefore SecΘTanΘ = - Tan²Θ
