Re: Sin, Cos, and Tan

is it the "sin" with the negative 1 exponent?

Re: Sin, Cos, and Tan

Yes, try that. See if you can get yourself into degree mode, instead of radians.

Re: Sin, Cos, and Tan

im using the windows calculator and i got about 53 degrees? why did you pick sin not cos or tan?

Re: Sin, Cos, and Tan

Do not worry, we are going to do them too. Yes you should get around 53.13°

Congratulations you did some trig. You found A! Just for fun what is B?

Re: Sin, Cos, and Tan

soo 3/5 = 36.87°

am i right i used sin can you explain to me why i picked sin to get a?

Re: Sin, Cos, and Tan

I have no idea really, maybe you like sine? I would have picked tangent.

Here is a trick for B. The sum of the angles in a triangle are 180°. So 180 - 90 - 53.13 = 38.87°

Re: Sin, Cos, and Tan

How could you say that. You just got 2 right answers! What do you say when you get wrong answers?

Let's get A using tangent.

Wait! Where did he go? The tangent function does that to a lot of people.

Re: Sin, Cos, and Tan

Oh, sorry, you are here. Thought that  horrible tangent got ya.

Okay, what do you get for A using tangent?

oh so the sine is equal to the tan
let me see about the cos

Re: Sin, Cos, and Tan

Okay, sin, tan , cos are really just the relationship of the angles of a triangle and it sides. Give me some time, I am putting a problem for you together.

Re: Sin, Cos, and Tan

soo the first problem the triangle is an iscoseles triangle? cause both sides equal the same right? or not? and do the sin and tan and cos have diffrent purposes or can you use them all?

Re: Sin, Cos, and Tan

If I am looking at angle of 37°, how high off the ground is my cat? The distance from the cat on the ground is 100 ft.

Re: Sin, Cos, and Tan

tan(37°) = opposite / adjacent

tan(37°) = opposite / 100

Does that help?
