Question

if 2sinA=1. then find the value of tanA​

Answer 1

Answer:

1/✓3

Step-by-step explanation:

sin A=1/2

sinA=sin30

A= 30

tanA=tan30

= 1/✓3

Answer 2

Answer:

$tanA = \frac{1}{ \sqrt{3} }$

Step-by-step explanation:

2sinA = 1

sinA = 1/2

$\cos(A) = \sqrt{1 - {sin}^{2}A} \\ = \sqrt{1 - ({sinA})^{2}} \\ = \sqrt{1 - { (\frac{1}{2} )}^{2} } \\ = \sqrt{1 - \frac{1}{4} } \\ = \sqrt{ \frac{3}{4} } = \frac{ \sqrt{3} }{2}$

Also,

$tanA = \frac{sinA}{cosA} \\ = \frac{ \frac{1}{2} }{ \frac{ \sqrt{3} }{2} } \\ = \frac{1}{2} \times \frac{2}{ \sqrt{3} } \\ = \frac{1}{ \sqrt{3} }$
