am getting 12/13, am i correctIntegral said:Once you have drawn the triangle it is easy. Mark the angle represented by ArcTan [itex] \frac 5 {12} [/itex]
then use the definition of the cos of that angle to get your answer.
Correct. BTW, if you're allowed access to a calculator, you can use that to verify your answer (even if you're not allowed to use the calc to derive the answer).jacy said:am getting 12/13, am i correct

No, trig ratios have no unit. You're dividing a length by a length, so they're dimensionless.jacy said:Thanks, should the unit be the length of the sides, since 12/13 is not an angle.
