Question

tan^-1(sqr3/3) i dont have the calculator for this one.

Answer 1

30 degrees or pi/6

Answer 2

i have to find the angles that fit the expression

Answer 3

Actually, if you have Google, you have a calculator. For example, google arctan (sqrt 3/2) and get arctan(sqrt(3) / 2) = 0.713724379 rad

Answer 4

And if that doesn't do it, there's always Wolfram Alpha: http://www.wolframalpha.com/

Answer 5

thank you but i stuck finding the angles that fit the expression

Answer 6

what expression?

Answer 7

For that matter, if you're on Windows, you have a built-in scientific calculator that would be more than enough for this. Just choose scientific from the view menu on the standard windows calc.

Answer 8

i have to find the angle values that fit the expression.

Answer 9

If you're looking for the angles, then you just run the inverse function to solve for the angle.

Answer 10

On Windows, the inverses are sinh, cosh, tanh.

Answer 11

i got 33.869

Answer 12

Did you mean to type \[\theta = \tan^{-1} \frac{\sqrt{3}}{3}\]

Answer 13

Because that give me an even 30 degrees.

Answer 14

yes that what i ment i dont know how to imput it on here

Answer 15

Ah, use the equation button. The syntax is called LaTeX, but you don't need to know it to use the editor. So solve in this order:

\[\sqrt{3}\]
Divide that by 3.
Press the arctangent button (tanh, atan or cot, depending on your calculator)

Answer 16

You should then get the same answer.

Answer 17

thanks

Answer 18

No problem.
