Priya . 4 years, 2 months ago

Since all the options involve the trigonometric ratio tan θ, so we use the identity 1 + tan2θ = sec2θ. To find: sec4A – sec2A Consider sec4A – sec2A = (sec2A)2 – sec2A Now, as sec2A = 1 + tan2A ⇒ sec4A – sec2A = (sec2A)2 – sec2A = (1 + tan2A)2 – (1 + tan2A) = 1 + tan4A + 2 tan2A – 1 – tan2A = tan4A + tan2A

Sia ? 4 years, 2 months ago

Coordinate of Point R is ( 4 , 3 ).

Step-by-step explanation:

Given Coordinates of the Points are

P ( 1 , 0 ) , Q( 4 , 0 ) and S( 1 , 3 )

We need to find: Coordinate of the point R such that PQRS is a Square.

First we mark all the given points on the Graph.

Then see where the Point R lies satisfying that PQRS is a Square.

1st Graph Attached has all 3 given point marked.

Clearly from graph 1. Coordinate of Point are must be on line x= 4 and y = 3

So, Coordinate of point R is intersection of lines x = 4 and y = 3

that is (4 , 3).

Therefore, Coordinate of Point R is ( 4 , 3 ).

Dear Diary:

Today I am going to share with you my feelings about my visit to a school for the blind. The school conducted this trip as a part of social service and moral education class. I was really moved to see these special children with visual disabilities. I saw them studying with unique focus. Though technology has developed special audio and Braille books for them, but still their deprivation was tangible. The one thing I liked the most about them was their zest for life. They seemed to be least affected by their deprivation. Interacting with them I felt so humble! I also realized how fortunate I am to have this blessing of vision. I wish all those children and all the people in the world who are suffering from visual deprivation all the success, health, and contentment. God bless all of them!

Because diffusion is a very slow process and multi cellular beings are very complicated in their structure, hence it would take a very long time for the diffused oxygen to reach all the parts of the body.
