The future of the Universe will be determined by the struggle between the momentum of its expansion and the pull of gravity. ... The vertical scale indicates the size of the Universe. For the next several billion years, the expansion of the Universe gradually slowed down due to the effects of gravity on matter.
Ok I’m going to work on this it might take me awhile so bare with me
An example of basic trigonometric functions question is find tan
.
<h3>What are trigonometric functions?</h3>
The term trigonometric function is known to be made up of functions such as sine (sin), cosine (cos), tangent (tan), etc., that stands for the ratios of sides of all right triangles.
To solve for tan 
It will be
= 2
+ 
θ = 
θ = 
To know the right angle,
θ =
x 180/4 = 45⁰
tan θ = 1
Therefore, tan
= -1
