The functions sine, cosine and tangent of an angle are sometimes referred to as the primary or basic trigonometric functions.
How do you simplify (sec x - cos x) / tan x? - Socratic
2015年8月22日 · sinx This can also be proven by showing that secx-cosx = (tanx)(sinx) and then dividing both sides by tanx Let's start by breaking down some terms. In my opinion, you have to kind of play around with trig stuff to get it to break down right. secx=1/cosx=tanx/sinx So, (secx-cosx)/tanx = secx/tanx - cosx/tanx = (tanx/sinx)/tanx - cosx/tanx =1/sinx - cosx/tanx Tangent = …
