Question

IS this an acceptable answer?
Find the exact value of the expression.
3sin45 degrees - 4tan(pi/6)
I said ((3rad2)/2) - (4/rad3)
Do I have to combine it or take the radical out of the denominator?

Answer 1

i would take the radical out of the denominator just to make it look a little nicer.

Answer 2

what in the world??!!

Answer 3

right now you have:
\[\frac{3\sqrt{2}}{2} - \frac{4}{\sqrt{3}} = \frac{3\sqrt{2}}{2}- \frac{4\sqrt{3}}{3}\]
if you wanna go further than that, its your call.

Answer 4

what kind of idiot math teacher has both degrees and numbers in the same problem?

Answer 5

lololol, i didnt even notice that.

Answer 6

let me just shut up. there is no end to bad math instruction

Answer 7

a teacher that covers his/her bases, im for deg/rad equality!

Answer 8

like saying square 3 degrees celsius, add 2 degrees kelvin and then subtract the square root of 64 degrees fahrenheit

Answer 9

hahaha! take it up with my teacher

Answer 10

its like all the people on this site trying to solve physics problems using g = 9.81 m/s^2 when distances are given in ft >.>

Answer 11

no just pass the class and hope your next instructor knows some mathematics

Answer 12

It's just busy work

Answer 13

this is kinda my next instructor, it's for a summer assignment. so i still have her for a whole year.

Answer 14

yeah don't take it to heart. @joemath i like the ones where the ball gets hit by a bat and you are supposed to assume it goes straight up!

Answer 15

@elizac when you feel more confident just ask in a meek tone how come one input is given by numbers and the other with degrees attached? say "just curious but..."

Answer 16

you should bring it up in class. not in a rude way, be chill about it lol.
@Satellite lol, we have some skilled batters haha

Answer 17

"i just happened to notice that..."
