There are three reciprocal trigonometric function, making a total of six including cosine, sine, and tangent.
The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta).
The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).
The conventional way to define the trig functions is to start with an acute angle that is an angle with measure/theta between 0 and 90 degrees.
