Question

if sinΦ=1/2 find 2tanΦ/1+tan²Φ​

Answer 1

Answer:

sinπ=1/2

then π=30°

therefore 2(tan30°)/1+tan^2(30°)

=(2/√3)/1+1/3

=(2/√3)/4/3

=2/√3* 3/4

=√3

please comment

Answer 2

Step-by-step explanation:

$sin \alpha = \frac{1}{2} \\ \alpha = {30} \\ \frac{2tan \alpha }{1 + {tan}^{2 } \alpha } = \frac{2tan30}{1 + {tan}^{2}30 } \\ \frac{2 \frac{1}{ \sqrt{3} } }{1 + \frac{1}{3} } = \frac{6 + \sqrt{3} }{4}$
