Question

sinA=cosA then the value of 2tanA+cosA^=??​

Answer 1

Answer:

ANSWER IS 2+COS A

Step-by-step explanation:

GIVEN: SINA=COSA

TO PROVE 2TANA+COS A=?

PROOF:

2tanA + cos A

2sinA÷cosA+cos A

2cos A÷ cos A+cosA

2(1)+cosA

2+ cos A

Answer 2

Answer:

Step-by-step explanation:TRIGONOMETRIC REDUCTIONS ★

Given that :

Sin θ = Cos θ

Possible for only one set

θ = π / 4

Now , required value : 2Tanθ + Cos²θ

2 Tan45° + Cos²45°

2 ( 1 ) + 1/2

5/2
