Cot is cos/sin

WebThe cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . This is an online free cot calculator. You can calculate value of cot() trignometric function easily using this tool. Important Abbreviations to remember. SOH: Opposite / Hypotenuse (Sine) CAH: Adjacent / Hypotenuse (Cosine) Websin stands for sine.cos stands for cosine. cosine is the co-function of sine, which is why it is called that way (there's a 'co' written in front of 'sine').Co-functions have the relationship sin@ = cos(90-@) However, the trig function csc stands for cosecant which is completely different from cosine.As you might have noticed, cosecant has a 'co' written in front of …
