Pd).
cot x/sec x
show that -=cos ecx -sin x

see explanation

Step-by-step explanation:

Using the trigonometric identities

• cot x =

• sec x = and cosec x =

Consider the left side

= × cosx

=

=

= -

= cosec x - sin x

= right side ⇒ verified

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 "
