Question

If sin A = cos A, then the value of 2 tan A + cos^2 A is:​

Answer 1

Answer:

Since sin A = cos A

value of A = 45°

Check the attached file for more information.

Tan A = Tan 45° = 1

Cos A = Cos 45° = 1/√2

So,

2*1 + (1/√2)^2 = $2 + 1/2$ = 5/2 = 2.5

You can keep the answer as a fraction or convert it into decimal as per your choice

Answer 2

Answer:

Since sin A = cos A

value of A = 45°

Check the attached file for more information.

Tan A = Tan 45° = 1

Cos A = Cos 45° = 1/√2

So,

2*1 + (1/√2)^2 =
