这个公式的意思是,如果我们有一个角度θ,那么cos(π/2 - θ)的值就等于sin(θ)的值。 解释: 中文:这个公式告诉我们怎样把余弦函数转化成正弦函数。我们只需要把原来的角度从π/2中减去,然后取余弦,就得到了相应的正弦值。 英文:This formula shows us how to convert a cosine function into a sine functio...
The formula for the X coordinate isradius + (radius * cos(degree)). Let’s plug that into our new--_xvariable: --_x:calc(var(--_r)+(var(--_r)*cos(var(--_d))); The formula for the Y coordinate isradius + (radius * sin(degree)). We have what we need to calculate that...
