Question

If sinA=cosA then find the value of 2tanA + cos²A.​

Answer 1

Step-by-step explanation:

tanA = 1

A = 45°

CosA = 1/√2

2tanA+ Cos^2A = 2+ 1/2= 5/2

Answer 2

Answer:

$2 { \tan(a) } + { \cos(a) }^{2}$

$2 \frac{ \sin(a) }{ \cos(a) } + { \cos(a) }^{2}$

$\sin(a )= \cos(a)$

$2 \frac{ \sin(a) }{ \sin(a) } + { \cos(a) }^{2}$

$2 + { \cos(a) }^{2}$
