Homework Equations
deriv. of tan(pi/3)
The Attempt at a Solution
How can I solve this? I am not supposed to use a calculator?? tan(pi/3) ...am I supposed to memorize this?
The derivative of tan(pi/3) is zero. tan(pi/3) is a constant, and the derivative of any constant is zero.Homework Statement

Yes. There are a few angles whose trig functions you should have memorized - 0, pi/6, pi/4, pi/3, pi/2, as well as their supplements and combinations with pi/2, pi, and so on. You should also have memorized all of the six trig functions in terms of the sine or cosine.The Attempt at a Solution
