Question

if tanA=2 evaluate secA sinA + tan^2 - cosec A​

Answer 1

Answer:

tan A = perpendicular/ base

so , perpendicular = 2

base = 1

hypotenuse = √5

therefore , sin A = 2/√5

sec A = √5/1

tan A = 2/1

cosec A = 2/√5

thus , secA sinA + tan^2 - cosecA

= √5/1× 2/√5 + ( 2/1)^2 - 2/√5

= 2 + 4 - 2/√5

= 6 - 2√5

Answer 2

Answer:

you know that tan a = of a divided by adjacent and by doing that we can find out there and by doing and substituting that we can find the answer and all these connectors and letters will get answer
