Question

2. Find value of tanA, if sinA=1\2

​

Answer 1

Sin A = 1/2

This means that the value of A is 30 degree,

Tan 30=

$1 \div \sqrt{3}$

Answer 2

Answer:

SinA = 1/2

Step-by-step explanation:

cosA = √(1 - sin^2A) = √(1 - 1/4)

CosA = √(3/4) = √3/2

TanA = SinA/CosA

TanA = (1/2)/(√3/2) = 1/2 * 2/√3

TanA = 1/√3 Answer

second method:

sinA = 1/2 => SinA = Sin30°

=> A = 30°

so TanA = Tan30° = 1/√3 Ans
