Question

Hey guys help me

If sinA=cosA find the value of (2tanA+cosA).​

Answer 1

here is your answer Mate!!

Hope it helped;-)

Answer 2

According to the Question

Sin A = Cos A

Hence

$\bf\huge\frac{Sin\:A}{Cos\:A} = 1$

Tan A = 1

Tan A = Tan 45

A = 45

Now here

2 Tan A + Cos A

2 Tan 45 + Cos^2 45

$\bf\huge = 2\times 1 + \frac{1}{\sqrt{2} }$

$\bf\huge = 2 + \frac{1}{2}$

$\bf\huge = \frac{4 + 1 }{2}$

$\bf\huge = \frac{5}{2}$
