need answer to a simple math problem...

[MrDingleDangle]

i know this is easy...cant do it on the computers calculater

7/20=sin(x/2)

 

[59Vette]

2sin^-1(7/20)

 

[59Vette]

actual answer = me too lazy to get mine, sorry

 

[MrDingleDangle]

thanx, but its the actual answer i need

 

[somethingwitty]

assuming I'm supposed to be in degree mode (im never sure...)

inverse sin (7/20) = 20.48731511.....

that * 2 = 40.97463.....(x)

 

[MrDingleDangle]

thanx

 

[somethingwitty]

no prob. like i said, though-have someone confirm that degree mode is right...im never sure, degree or radian

Maybe it is just me but if it is simple math shouldn't you be able to do it on your fingers and toes?

I used to hate that back when I was a freshman and sophmore in college. In Calc, almost everything was in radians, but in physics everything was in degrees. I would always forget to change the mode and end up getting the wrong answer. The good thing is that it is usually really easy to tell when you are using the wrong mode.

i believe it's in radians cause it's 7/20.. they usually say degrees if it's in degrees
