What is the period of the function y = cos3x?
2pi / 3 supplement: the period of y = cosx is 2pi, so the period of y = cos3x is 2pi / 3
The minimum positive period T of function y = cos3x=______ ．
The minimum positive period T of the function y = cos3x is 2 π 3, so the answer is 2 π 3
The differential of y = arcsinx / X
