Question

Find the value of Arctan 1 @mathmale

Answer 1

"arctan 1" asks, "What is the angle whose tangent equals 1?"

Answer 2

How is the tangent function defined?
Remember that the sine is defined as the ratio opp/hyp.

Answer 3

45° ?

Answer 4

yep

Answer 5

Kenny has done a very nice job of graphing a triangle in the 1st Quadrant with opp side = 1 and adj side = 1.

Yes, that angle is 45 degrees. Mind explaining how you got that?

Answer 6

me?

Answer 7

Thanks, Kenny, but I meant Ms. Diaz. :)

Answer 8

okay :)

Answer 9

and congratulations for your purple :)

Answer 10

I used this!

Answer 11

Thank you!

@tdiaz1995 : how would you define the tangent function?
How did you use your unit circle to decide that the angle x is 45 degrees in this problem?

Answer 12

that table has served you well. But it'd be worth learning the 30-60-90 and 45-45-90 triangles also. Familar with them yet?

Answer 13

@mathmale unit circle is not required

Answer 14

Yeah, I memorize them before Spring Break! :D

Answer 15

It's important that we guide others in the use of approaches that are familiar to them, as the unit circle is familiar to Ms. Diaz. Later we can introduce faster methods.

Answer 16

Pero sabes porqué es 45?

Answer 17

En luego de sólo los memorizar?

Answer 18

OK, Kenny still wants to know how you got 45 degrees for x.

Answer 19

Sólo use la tabla! En realidad no sé por qué es 45°, saben hablar Español? :o

Answer 20

pista: el triangulo es isosceles

Answer 21

:)

Answer 22

Thank you for working together respectfully.

Answer 23

Hmmm, porque el triangulo isosceles es de 45°? Estoy en lo correcto? Can you guys explain me why?!?! You're welcome @mathmale! :D

Answer 24

Exactamente :)

Answer 25

Muchas gracias a los dos! I'll do another question because I'm not sure if I got the correct answer! I'll tag you guys to see which one of you can help me, please!

Answer 26

En realidad preferirias espanol o ingles?

Answer 27

My first language is Spanish! I can understand English but, I think that I'm not that good writing it! Do you understand well both languages?

Answer 28

Pienso que si

Answer 29

En realidad pienso que escribis bien ingles

Answer 30

Thank you! Which one do you prefer?

Answer 31

Mi ingles es mejor que mi espanol, pero me gustaria lo practicar, entonces prefiero hablar espanol
