Answer:

Rule : When we rotate a figure of 90 degrees clockwise, each point of the given figure has to be changed from (x, y) to (y, -x) and graph the rotated figure. Let us look at some examples to understand how 90 degree clockwise rotation can be done on a figure.

If the nth term of a number sequence is n squared-3 if the first 3 terms and the 10th term

iragen [17]

Answer:

First three terms: -2, 1, 6

Tenth term: 97

Step-by-step explanation:

Given

$T_n =n^2 -3$

Required

The first three terms and the tenth

So, we have:

First term: n =1

$T_1 = 1^2 - 3 = 1 - 3 = -2$

Second term: n = 2

$T_2 = 2^2 - 3 = 4 - 3 = 1$

Third term: n = 3

$T_3 = 3^2 - 3 = 9 - 3 = 6$

Tenth term: n = 10

$T_{10} = 10^2 - 3 = 100 - 3 = 97$

What is theTan(pi/2)

zhenek [66]

Answer:

Undefined.

Step-by-step explanation:

Comment

Let's begin by discussing why a calculator throws up and gives an error when Tan(pi/2) is entered.

Start by entering Tan(89) which is 1 degree from pi/2. The calculator is very well behaved when you do that, but look at how big Tan(89) is. 57.29. That's pretty big as these things go.

I was taught that the answer to Tan(pi/2) was infinity which I think is no longer in vogue. I think you should be answering Undefined.
