    Hakan, Thanks for finding this error. The correct answer to Q.8 in EXS_2-7(6) exercise set is approximately 1.29 (your answer). I've corrected the exercise set and uploaded it above (version 2). Thanks, Tim

    Definitely. Thats what I though but I wanted to make sure.
  • Suzhen, Thank you for your feedback. You are correct, the answer to #8 on EXS_2-5-30v1 should be -2, not 2. And, there is something incorrect for #7. I will make a correction soon and post it here. Thanks very much for pointing these out.

    Jarrod, Excellent question. I was taught (and I teach my students) that whenever differentiating or integrating trigonometric functions then the functions must be evaluated using radians because radian measure is 'unitless' (it's just a ratio)...

    HL Problem of the Day
    Can you help in problem #160? When we plug in 60 degrees or pi/3 we get teh same answer for the first step. How do we know our answer is in radians/ hour and then have to convert?
