`sin theta = sqrt3/2`

We know `sin theta = "opposide side"/"Hyotence" = sqrt3/2`

Now consider right-angled Δle ABC

Let x = adjacent sidead

By applying Pythagoras

ЁЭР┤ЁЭР╡2 = ЁЭР┤ЁЭР╢2 + ЁЭР╡ЁЭР╢2

4 = 3+ЁЭСе2

ЁЭСе2 = 4 − 3

ЁЭСе2 = 1

ЁЭСе = 1

`cos = "opposite side"/"Hypotenuse" = 1/2`

`tan = "Oppsite side"/"hypotenuse" = sqrt3/1 = sqrt3`

`cosec theta = 1/sin theta = 1/(sqrt3/2) = 2/sqrt3`

sec = `1/cos theta = (1/1)/2 = 2`

`cot = 1/tan theta = 1/sqrt3`
