Find the components of the vector A⃗ with length a = 1.00 and angle α=10.0∘ with respect to the x axis as shown.

I can't display the figure obviously, but I figured 1 x cos(10) and 1 x sin(10) would give the two components I need, but I'm still getting the wrong answer.

  1. Yes, assuming your vector is 10 degrees above the x axis in the first quadrant your answer is correct. Be sure you have it to 3 significant figures since both 1.00 and 10.00 are three significant figures.

    1.00 cos 10.0 = 0.985
    1.00 sin 10.0 = 0.174
