Find the exact value of cos 60* - cot 30* - cot 90*.

½ - sqrt(3)

Step-by-step explanation:

cos(60) = ½

tan(30) = 1/sqrt(3)

cot(30) = sqrt(3)

tan(90) is undefined

cot(90) = 0

½ - sqrt(3) -0

½ - sqrt(3)

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
