Question

( 1+tanA+secA)(1+cotA-cosecA) = ?​

Answer 1

Answer:

$\mathbf{\color{purple}{\huge{✮}}}\mathbf{\blue{\huge{A}}}\mathbf{\color{aqua}{\huge{N}}}\mathbf{\green{\huge{S}}}\mathbf{\color{yellow}{\huge{W}}}\mathbf{\orange{\huge{E}}}\mathbf{\red{\huge{R}}}\mathbf{\color{maroon}{\huge{✮}}}$

cotA=cosA/sinA

cosecA=1/sinA

tanA=sinA/cosA

Identity: sin^2A+cos^2A=1
