It is given that sin (π/2 θ/3) = √3/2 Formula Used Basic concept of trigonometric ratio and identities We know that sin(90 θ) = cosθ ⇒ cos30° = √3/2 Calculation We know that sin (π /2 θ) = cos θ ∴ sin(π/2 θ/3) = √3/2 ⇒ cos(θ/3) = cos 30 ° ⇒ θ/3 = 30 ° = θ = 90 ° Now, value of tan θ = tan 90 ° = NotStarting with θ = 0, θ = 0, we calculate the first yvalue, add the length of the interval π 2 π 2 to 0, and calculate the second yvalue We then add π 2 π 2 repeatedly until the five key points are determined The last value should equal the first value, as the calculations cover one full periodUsing the above table, values of sin π/6, cos π/6, tan π/6, sin π/4, cos π/4, tan π/4, sin π/3, cos π/3, tan π/3, sin π/2, cos π/2, and tan π/2 in radians could be easily found out A trigonometric table has wide application in fields like science and engineering A few key points that can be noted in the trigonometric table are,
