Note: π = 180.
Given Equation is 3 sin(π/6) sec(π/3) - 4 sin(5π/6) cot(π/4)
⇒ 3sin(180/6) * sec(180/3) - 4sin(5*180/6) * cot(180/4)
⇒ 3sin(30) * sec(60) - 4sin(150) * cot(45)
⇒ 3 * (1/2) * (2) - 4 * (1/2) * (1)
⇒ 3 - 2
⇒ 1.
Hope it helps!

how does sin150 become 123
1/2
Sin(150) = sin(180 - 30). We know that sin(180 - A) = sinA. So, it will become sin(30) = 1/2
kk
