Solve sint = cos2t, for –4π ≤ t ≤ –2π
e-lub [12.9K]

Answer:

-(23/6)π

-(19/6)π

-3π

Step-by-step explanation:

cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t

sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0

Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,

sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π

Modern computers are built using the principle of Hierarchical layers of abstraction. Explain Hierarchical layers of abstraction
bearhunter [10]

Answer:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate  platform independence.

Step-by-step explanation:

Hierarchical layers of abstraction in computers:

Hierarchical layers of abstraction in computers are used to hide information and manage deep functionality by allowing the separation to facilitate  platform independence.

In Hierarchical layers, users work independently at each level of the hierarchy.

example:

Abstraction in computing is language abstraction

Development of programming languages from machine language to  assembly language and then high-level language is an example of  Hierarchical layers of abstraction. Here each stage is a base for the next stage.
