Question

What is value of
1 + tan²A.

Answer 1

Answer:

Answer:1+tan^2A= sec^2A.

Answer:1+tan^2A= sec^2A.Internal Information :-

Sin (– θ) = – Sin θ

Cos (– θ) = Cos θ

Tan (– θ) =– Tan θ

Sec (– θ) = + Sec θ

Cot (– θ) = – Cot θ

Sec (90o + θ ) = Cos θ

Cot (90o – θ ) = Cos θ

Tan (90o + θ ) = – Cot θ

Tan (90o – θ ) = Cot θ

Sec (90o + θ ) = Cosec θ

Sec (90o + θ ) = Cosec θ

Sin (270o – θ ) = – Cos θ

Sin (270o – θ ) = – Cos theta

sin2 A+cos2 A=1

sec2A-tan2 A=1

cosec2A-cot2A=1

$value \: of \: 1 + {tan}^{2}A\: is \: 1 + { \tan }^{2} A = { \sec }^{2}A$
