The inverse functions of sine, cos and tan functions are csc, sec and cot respectively.
<u>Step-by-step explanation:</u>
The reciprocals of sine, cos and tan functions are csc, sec and cot functions. The reciprocal of cosine function is secant, (sec) sec θ =
The inverse or reciprocal function is cosecant (csc),
The inverse tangent function is cotangent (cot) , expressed in two ways: or
So then its reciprocal or inverse is termed as cot θ.
