Horizontal Projectiles. Degree or Radian mode in calculator?

    1. The problem statement, all variables and given/known data
    It's a worksheet with questions like : A pelican flying along a horizontal path drops a fish from a height of 5.4 m. The fish travels 8.0 m horizontally before it hits the water below. What is the pelican's initial speed?

    2. Relevant equations

    3. The attempt at a solution

    So should I have my calculator in radian or degree mode?

    Use whichever mode the problem requires: If given angles are in degrees or if a result is required in degrees, set the calculator to Degrees. Set it to radians if you need to work with radians. Also, you can always convert from one to the other via suitable constants.
