For L=cos(2πt/3)160e^(-0.125t)
show that the times of maximum are given by some solutions of the equation:
tan(πt/6)=-(1/2π) t∈[0,20]
show that the times of maximum are given by some solutions of the equation:
tan(πt/6)=-(1/2π) t∈[0,20]
请先把你的等式写清楚,哪些在分子上,哪些在分母上。
a
o(∩_∩)o...写清楚点啊,这样谁看得懂啊。
cos(2πt/3)
tan(πt/6)
三角公式划一下,在看160e^(-0.125t)
不就好了吗
