Which value is the solution for the equation tanx/2=1
pi/2
pi/4
3pi/4
3pi/2

Answer 1

a ) π/2, 4π/3, 3π/2. 5π/3.

Explanation:

2 sin t cos t + √3 cos t = 0

cos t ( 2 sin t + √3 ) = 0

Therefore:

cos t = 0, t 1 = π/2, t 2 = 3 π/2

or:

2 sin t + √3 = 0

2 sin t = - √3

sin t = - √3 / 2

t 3 = 4 π/3, t 4 = 5 π/3

Answer 2

I think its the first option
